https://doi.org/10.1109/TVCG.2016.2642109. About. Figure 4.15 demonstrates a non-continuous cartogram of US population in 2014 from Olson, J. M. (1976). 0. The USAboundaries package is great for obtaining map data for the United States at any point in history (Mullen and Bratt 2018). That said, there are benefits to using plotly-based maps since the mapping APIs are very similar to the rest of plotly, and you can leverage larger plotly ecosystem (e.g., linking views client side like Figure 16.23). For example in the following map we hide all physical features except rivers and lakes, neither of which are shown by default: In addition to physical base map features, a "cultural" base map is included which is composed of country borders and selected sub-country borders such as states. There are actually 4 different ways to render sf objects with plotly: plot_ly(), plot_mapbox(), plot_geo(), and via ggplot2’s geom_sf(). p <- plot_geo (df) %>% add_trace (z = ~GDP..BILLIONS., color = ~GDP..BILLIONS., colors = 'Reds', text = ~COUNTRY, locations = ~CODE, marker = list (line = l)) %>% colorbar (title = 'GDP (log)') %>% layout (title = '', geo = g) print (p) To create a map with your own cultural features please refer to our choropleth documentation. charts, plots, maps and diagrams) represented by data structures also referred to as figures. Choropleth Map: World. A dorling cartogram sizes the circles proportional to some metric (e.g., population). name), as done in Figure 4.10. “Maps of the 2016 Us Presidential Election Results.” Blog. heatmaply: the most flexible option, allowing many different kind of customization. A number of other R packages provide cartogram algorithms, but the great thing about cartogram is that all the functions can take an sf (or sp) object as input and return an sf object. 2019. It is used to represent spatial variations of a quantity. Plotly is great for its interactivity on visualizations! Creating a Choropleth Map of the World in Python using GeoPandas. Get Pricing Specifically, by default, plotly attempts to render all simple features in a single trace, which is performant, but doesn’t have a lot of interactivity. Hot Network Questions Why are there double hinge lines on the rudders of the Grumman C-2? Supplemental Materials - http://www.superdatascience.com/learn-plotly/Welcome back to our Working With Plotly series! Our first Plotly map! Simple Plotly Tutorials.  |  PROJ contributors. It is based on the JavaScript library D3.js. We will use Plotly’s geographical map to plot India and its neighbours on a choropleth map. Learn about how to install Dash at https://dash.plot.ly/installation. It displays world population data downloaded from the World Bank databank. R: A Language and Environment for Statistical Computing. Note: Plotly Express cannot create empty figures, so the examples below mostly create an "empty" map using fig = go.Figure(go.Scattergeo()). The darker the shade, the greater the quantity (the higher the value, the tighter the dispersion, etc.). We'll be using plotly Scattergeo() method available from plotly.graph_objects module. We will use the express module of Plotly conventionally called px. A couple notable examples include rnaturalearth and USAboundaries. For example, a given trace can only have one fillcolor, so it’s impossible to render multiple polygons with different colors using a single trace. It is used to represent spatial variations of a quantity. Since we plot the map to show the COVID-19 cases around the world, we set the locationmode to “country names”. Please consider donating to, # or any Plotly Express function e.g. 2018. Reply . In a previous notebook, I showed how you can use the Basemap library to accomplish this.More than 2 years have passed since publication … Figure 4.9 augments the print method for sf to data frames to demonstrate that all the information needed to render the countries (i.e., polygons) in Figure 4.8 is contained within the world data frame. The map is interactive, so have a look zooming, panning, looking at the markers and isolating each plot by clicking on the legends. 3 Plot the map Finally, we can plot the data on to a 3D globe using the plot_geo command in plotly. A popular class of contiguous cartograms that do not preserve shape are sometimes referred to as tile cartograms (aka tilegrams). R Core Team. See the code of the chart beside here. Plotly Express makes it much faster to create plots. Plotly Geo maps have a built-in base map layer composed of "physical" and "cultural" (i.e. Dorling, D. 1996. heatmaply: the most flexible option, allowing many different kind of customization. Plotly Geo maps have a built-in base map layer composed of "physical" and "cultural" (i.e. Various lines and area fills can be shown or hidden, and their color and line-widths specified. Plotly Express ’ px.choropleth function and the lower-level go.Choropleth graph object can create choropleth maps and you can find some examples on the official website. For the interactive, see https://plotly-r.com/interactives/satellite.html, Figure 4.3 demonstrates how to create an integrated plotly.js dropdown menu to control the basemap style via the layout.updatemenus attribute. Generally speaking the approaches fall under two categories: integrated or custom. It can plot various graphs and charts like histogram, barplot, boxplot, spreadplot and many more. Animated choropleth world map Conclusion Introduction. The next example is a "strictly native" approach that leverages the layout.geo attribute to set the aesthetics and zoom level of the map. On the other hand, Matplotlib and Plotly can do much more than just plot data on maps. The "usa" scope contains state boundaries at both resolutions, and uses the special 'albers usa' projection which moves Alaska and Hawaii closer to the "lower 48 states" to reduce projection distortion and produce a more compact map. This makes it incredibly easy to go from raw spatial objects, to transformed objects, to visual. As explained in step1, reading the data as .csv file from the repository. It’s possible to achieve the same effect using plot_ly() or plot_mapbox(), but the relevant marker/line/polygon data has to be put into an sf data structure before rendering (see Section 4.2.1 for more details). Geocomputation with R. Chapman and Hall/CRC. You can then manually save this as a .png. More than 2 years have passed since publication and the available tools have evolved a lot. There are numerous packages for accessing geo-spatial data as simple features data structures. Currently this attribute must be a URL pointing to a geojson file. For the interactive, see https://plotly-r.com/interactives/mapbox-bubble.html. We would like to know where Brazilians are traveling more often. 1. The plotly Python package exists to create, manipulate and render graphical figures (i.e. A classic example of this misleading effect in action is in US election maps – the proportion of red to blue coloring is not representative of the overall popular vote (Newman 2016). These functions render multiple polygons using a single trace by default, which is fast, but you may want to leverage the added flexibility of multiple traces. You can use Open Street Maps tiles in plotly dash with python and it is completely open source. Everywhere in this page that you see fig.show(), you can display the same figure in a Dash application by passing it to the figure argument of the Graph component from the built-in dash_core_components package like this: Sign up to stay in the loop with all things Plotly — from Dash Club to product updates, webinars, and more! In this case the layout.geo.visible attribute can be set to False to hide all base map attributes except those which are explicitly set to true. Through this website, one can search desirable projections for a given portion of the globe and extract commands for projecting their geo-spatial objects into that projection. import plotly.plotly as pl import plotly.graph_objs as gobj import pandas as pd from plotly.offline import download_plotlyjs,init_notebook_mode,plot,iplot init_notebook_mode(connected=True) Choose the 'Type' of trace, then choose 'Atlas Map' under 'Maps' chart type. This example shows how to create a choropleth world map with d3.choropleth. Figure 4.2 demonstrates the satellite earth imagery basemap. COVID-19 Dashboard | Part 5. I learned a new thing this week. FIGURE 4.5: A comparison of plotly’s integrated mapping solutions: plot_mapbox() (top) and plot_geo() (bottom). 2018. There are numerous types of cartograms and they are typically categorized by their ability to preserve shape and maintain contiguous regions. Plotly Choropleth With Slider (Map Charts Over Time) Follow. 2017. Heatmap with plotly.express and px.imshow¶. If you have fairly simple latitude/longitude data and want to make a quick map, you may want to try one of plotly’s integrated mapping options (i.e., plot_mapbox() and plot_geo()). “An Algorithm to Construct Continuous Area Cartograms.” The Professional Geographer. FIGURE 4.12: The population of various Canadian cities rendered on a custom basemap using a Mollweide projection. It’s worth noting that the locationmode is currently limited to countries and US states, so if you need to a different geo-unit (e.g., counties, municipalities, etc), you should use the choroplethmapbox trace type and/or use a “custom” mapping approach as discussed in Section 4.2. Plotly world Choropleth Map offline in python? administrative border) data from the Natural Earth Dataset. See the plotly book for more examples. As our intention is to getting familiar with the process of populating data in world map, we shouldn’t bother about this :P. Hmmm, yes, the resulted image raised my eyebrows too. Robin Lovelace, Jannes Muenchow, Jakub Nowosad. The map below uses all of these attributes to demonstrate the types of effect this can yield: The layout.geo.fitbounds attribute can be set to locations to automatically set the center and latitude and longitude range according to the data being plotted. 1. In addition, two datasets were used in this dashboard and they can be download from my github (← You can also find the dash app code here). Plotly - Heatmap - A heat map (or heatmap) is a graphical representation of data where the individual values contained in a matrix are represented as colors. 2018. Neha Kumar January 06, 2020 18:35. It displays world population data downloaded from the World Bank databank. In a previous notebook, I showed how you can use the Basemap library to accomplish this. Create scatter geo map chart in plotly dash. Command to install plotly: pip install plotly The end user can drag the slider across the bottom to see the colors on the heat map change year to year. The implementation behind Figure 4.15 is to simply take the implementation of Figure 4.14 and change cartogram_dorling() to cartogram_ncont(). The higher resolution allows us to zoom in better on more complex geo-spatial regions, but it allow leads to slower R code, larger HTML files, and slower responsiveness. Cartograms distort the size of geo-spatial polygons to encode a numeric variable other than the land size. I wanted to get a country name or code when I click on the country from the 3d globe as created above in r. What can I do to get a country code/name so that I want to filter my dataset on the selected country and draw another visualization for that country. A cartogram sizes the area of geo-spatial objects proportional to some metric (e.g., population). Plotly Express makes it easy to create animated graphs. Head to the 'style' dropdown, and adjust the marker size and color to your liking. For the interactive, see https://plotly-r.com/interactives/geo-flights.html. This enables us to set the Country column from new_df to locations parameter (Line 23–24). There are different ways of creating choropleth maps in Python. Here is a map with only cultural features enabled and styled, at a 1:50m resolution, which includes only country boundaries. However, the args provides the needed flexibility. FIGURE 4.7: Another map of U.S. population density, this time using choroplethmapbox with a custom GeoJSON file. See below for country sub-unit cultural base map features: Geo maps are drawn according to a given map projection that flattens the Earth's roughly-spherical surface into a 2-dimensional space. Plotting polygons on mapbox with plotly. The other integrated mapping solution in plotly is plot_geo(). 2016. Any plotting library can be used in Bokeh (including plotly and matplotlib) but Bokeh also provides a module for Google Maps which will feel very familiar to most people. https://CRAN.R-project.org/package=rnaturalearth. Dash Enterprise Overview. One way to perform the projection is to supply the relevant PROJ4 command to the st_transform() function in sf (PROJ contributors 2018). The color scheme automatically generated by Chart Studio can be changed within the TRACES popover. Figure 4.14 demonstrates a non-continuous Dorling cartogram of US population in 2014 from Dorling, D (1996). Pebesma, Edzer. Pebesma, Edzer J., and Roger S. Bivand. cufflink connects plotly with pandas to create graphs and charts of dataframes directly. Maps Won't Render - Using Rstudio, Plotly 4.9.0, Mapbox, geoJSON File. One nice thing about plot_geo() is that it automatically projects geometries into the proper coordinate system defined by the map projection. Write, deploy, & scale Dash apps and Python data visualizations on a Kubernetes Dash Enterprise cluster. choropleth is used to describe geographical plotting of USA. administrative border) data from the Natural Earth Dataset. For those interested in learning more about geocomputation in R with sf and other great R packages like sp and raster, Robin Lovelace (2019) provides lots of nice and freely available learning resources (Pebesma and Bivand 2005; Hijmans 2019). I decided to write a plot detailing how to plot a map of said murder rates in the US, but also adding a slider to explore the different years included in the data set. Select 'USA' for your scope and 'Albers usa' for type. For this, I … Dropdown menu for Plotly Choropleth Map Plots. How far the meanings of commonly used words can be redefined by legislature? It’s because the geo-spatial features are encoded in special (geometry) list-column. Creating a Choropleth Map of the World in Python using GeoPandas. This cartogram does not try to preserve the shape of polygons (i.e., states), but instead uses circles instead to represent each geo-spatial object, then encodes the variable of interest (i.e., population) using the area of the circle. Interactive maps with Python, pandas and Plotly: following bloggers through Sydney Jan 23, 2020 17 min read Tutorials Miscellaneous In this article and another few, I will explore Python and Plotly to put together a few different awesome looking charts. The thing is, plotly use its own low resolution world map. ¶ The first connection map that we'll create will depict flights from brazil to all other countries in the world. Lets change the focus of your map from the world to the USA. Plotly is a free and open-source graphing library for Python. Figure 4.13 demonstrates a continuous area cartogram of US population in 2014 using a rubber sheet distortion algorithm from James A. Dougenik, Nicholas R. Chrisman, Duane R. Niemeyer (1985). FIGURE 4.14: A dorling cartogram of US population in 2014. Do most amateur players play aggressively? Learn more about Plotly Dash. “Learning from and Improving Upon Ggplotly Conversions.” Blog. See https://plotly.com/python/reference/layout/geo/ for more information and chart attribute options! Plotly world Choropleth Map offline in python? January 10, 2021 47 comments. It’s worth noting that plotly aims to be a general purpose visualization library, and thus, doesn’t aim to be the most fully featured geo-spatial visualization toolkit. https://blog.cpsievert.me/2018/01/30/learning-improving-ggplotly-geom-sf/. Why QGIS crashes when I construct a QgsGraduatedSymbolRenderer object by QgsGraduatedSymbolRenderer.createRenderer() method? As far as geo mapping goes Matplotlib and Plotly look different (sometimes better) from the canonical Google Maps visual. First you’ll need the libraries: Prep & Reading Data (libraries, data file, API token etc.) In contrast to the Dorling cartogram, this approach does preserve the shape of polygons. Mainly used by data analysts to check the agriculture exports or to visualize such data. Choroplethmapbox is more flexible than choropleth because you supply your own GeoJSON definition of the choropleth via the geojson attribute. See the plotly book for more examples. https://www.R-project.org/. One can choose to create interactive data visualizations online or use the libraries that plotly offers to create these visualizations in the language/ tool of choice. Compared to plot_mapbox(), this approach has support for different mapping projections, but styling the basemap is limited and can be more cumbersome. Plotly’s graph_objects module contains Heatmap() function. Geographical plotting is used for world map as well as states under a country. We typically use the color in choropleths to encode a numeric variable (e.g., GDP, net exports, average SAT score, etc) and the eye naturally perceives the area that a particular color covers as proportional to its overall effect. 1. Get started. No Access token is needed for Open Street Map. Comparatively speaking, choroplethmapbox is more powerful because you can fully specify the feature collection using GeoJSON, but the choropleth trace can be a bit easier to use if it fits your use case. The map is plotted using Plotly’s graph_objs module that we imported. plotly: as described above, plotly allows to turn any heatmap made with ggplot2 interactive. Section 4.2 covers making sophisticated maps (e.g., cartograms) using the sf R package, but it’s also possible to make custom plotly maps via other tools for geo-computing (e.g., sp, ggmap, etc). The primary purpose o Step 4 Finalizing Your Graph. This is technically feasible, but much heavier and computationally … Various lines and area fills can be shown or hidden, and their color and line-widths specified. The plotly package comes with support for 7 different styles, but you can also supply a custom URL to a custom mapbox style. In addition, the named "scope" of a map defines a sub-set of the earth's surface to draw. This page documents how to build outline choropleth maps, but you can also build choropleth tile maps using our Mapbox trace types.. Below we show how to create Choropleth Maps using either Plotly Express' px.choropleth function or the lower-level go.Choropleth graph object. 2018. seaborn: Seaborn is a Python data visualization library based on matplotlib. Raster: Geographic Data Analysis and Modeling. FIGURE 4.13: A cartogram of US population in 2014. 1985. FIGURE 4.4: Using the integrated orthographic projection to visualize flight patterns on a ‘3D’ globe. In these cases, you may want to consider simplifying the geo-spatial object to improve the speed of the R code and responsiveness of the visualization. For this reason, if you want to vary the color of multiple polygons, make sure the split by a unique identifier (e.g. It is created using Python and the Django framework. You can set various properties of the map when instantiating a map object. The plot_geo() approach will transform line segments to correctly reflect their projection into a non-cartesian coordinate system. Some geo-spatial objects have an unnecessarily high resolution for a given visualization. PROJ Coordinate Transformation Software Library. Datasets used in Plotly examples and documentation - plotly/datasets It does get a bit trickier if you want to add interactivity using a dropdown, as you need individual colorscales for each layer. px.bar(...), Natural Earth policy regarding disputed borders, https://plotly.com/python/reference/layout/geo/. This page documents how to build outline choropleth maps, but you can also build choropleth tile maps using our Mapbox trace types.. Below we show how to create Choropleth Maps using either Plotly Express' px.choropleth function or the lower-level go.Choropleth graph object. On the other hand, the custom mapping approach offers complete control since you’re providing all the information necessary to render the geo-spatial object(s). “Noncontiguous Area Cartograms.” The Professional Geographer. It also uses the database world.cities from maps to filter the Brazilian cities and plot them on top of the "native" map. FIGURE 4.10: Using split and color to create a choropleth map of provinces in Canada. FIGURE 4.6: A map of U.S. population density using the state.x77 data from the datasets package. We show who actually controls the situation on the ground. Cartograms are an approach to reducing this misleading effect and grants another dimension to encode data through the size of geo-spatial features. ... plot(fig, validate=False, filename='d3-world-map.html', image='png') This actually creates an .html file and will open a browser. In addition to scatter traces, both of the integrated mapping solutions (i.e., plot_mapbox() and plot_geo()) have an optimized choropleth trace type (i.e., the choroplethmapbox and choropleth trace types). The geometry column tracks the spatial features attached to each row in the data frame. Hot Network Questions Why are there double hinge lines on the rudders of the Grumman C-2? In the default plotly template, a map frame and physical features such as a coastal outline and filled land areas are shown, at a small-scale 1:110m resolution: Here is a map with all physical features enabled and styled, at a larger-scale 1:50m resolution: In certain cases, such as large scale choropleth maps, the default physical map can be distracting. Here is a short tutorial on how to create an animated world map timeline using plotly.express choropleth. The sf R package is a modern approach to working with geo-spatial data structures based on tidy data principles (Pebesma 2018; Wickham 2014b). This allows each row to represent the real unit of observation/interest – whether it’s a polygon, multi-polygon, point, line, or even a collection of these features – and as a result, works seamlessly inside larger tidy workflows.14 The sf package itself does not really provide geo-spatial data – it provides the framework and utilities for storing and computing on geo-spatial data structures in an opinionated way. choropleth is used in the plotting of world maps and many more. 2018.  |  Section 4.2.2 covers how to render cartograms in plotly using sf and cartogram. Open Street Map is a project to create a free editable map of the world. We also saw how Plotly can be used to plot geographical plots using the choropleth map. Olson, J. M. 1976. If 'Lat/Lon' is chosen, specify the latitude (in degrees East) and longitude (in degrees North) cooordinates from the dropdown menus. You can only zoom in or out of the maps. ✊ Black Lives Matter. South, Andy. Wickham, Hadley. Figures 4.6 and 4.7 aren’t an ideal way to visualize state population a graphical perception point of view. Chamberlain, Scott, and Andy Teucher. Editors' Picks Features Deep Dives Grow Contribute. Vienna, Austria: R Foundation for Statistical Computing. To obtain all the pre-packaged basemap style names, you can grab them from the official plotly.js schema(): Any one of these values can be used for a mapbox style. “Area Cartograms: Their Use and Creation.” Concepts and Techniques in Modern Geography (CATMOG). Currently there are two supported ways of making integrated maps: either via Mapbox or via an integrated d3.js powered basemap. Generally speaking, you can treat these constructor functions as a drop-in replacement for plot_ly() and get a dynamic basemap rendered behind your data. Stay … The R package cartogram provides an interface to several popular cartogram algorithms (Jeworutzki 2018). import plotly.plotly as pl import plotly.graph_objs as gobj import pandas as pd from plotly.offline import download_plotlyjs,init_notebook_mode,plot,iplot init_notebook_mode(connected=True) Plotting The Neighbours. Is there an adjective describing a filter with kernel that has zero mean? This page documents how to build outline choropleth maps, but you can also build choropleth tile maps using our Mapbox trace types.. Below we show how to create Choropleth Maps using either Plotly Express' px.choropleth function or the lower-level go.Choropleth graph object. See the choropleth maps documentation for more information. The choropleth maps take two objects, (1) the data object and (2) … A Choropleth Map is a map composed of colored polygons. 2018b. Thankfully, there are nice resources for searching map projections in a human-friendly interface, like http://spatialreference.org/. Any help appreciated. So I downloaded high resolution world map from naturalearthdata.com and put in in GeoDataFrame world. In this case, each button uses the relayout method to modify the layout.mapbox.style attribute.13, FIGURE 4.3: Providing a dropdown menu to control the styling of the mapbox baselayer. 2016. Plotly is the library that has set the benchmark for interactivity for all the available map-visualization python libraries. I can't seem to make plotly not to use its own default map but to use my downloaded map instead. The next example is a "strictly native" approach that leverages the layout.geo attribute to set the aesthetics and zoom level of the map. With Plotly you can create beautiful Choropleth maps from the geo information. Note also, that sf provides special dplyr methods for this special class of data frame so that you can treat data manipulations as if it were a ‘tidy’ data structure. Although the integrated mapping approaches (plot_mapbox() and plot_geo()) can render sf objects, the custom mapping approaches (plot_ly() and geom_sf()) are more flexible because they allow for any well-defined mapping projection. Choropleth Map Using Python. Isn't that cool? Plotly is one of the finest data visualization tools available built on top of visualization library D3.js, HTML and CSS. Open in app. 4 thoughts on “3D world map with plotly” pranamya says: November 12, 2020 at 9:52 pm. Moreover, the location should point to a top-level id attribute of each feature within the geojson file. Maps Won't Render - Using Rstudio, Plotly 4.9.0, Mapbox, geoJSON File. Sf: Simple Features for R. https://CRAN.R-project.org/package=sf. The idea behind an integrated plotly.js dropdown is to supply a list of buttons (i.e., menu items) where each button invokes a plotly.js method with some arguments. “Tidy Data.” The Journal of Statistical Software 59 (10). Like your example choropleth, let's plot the current number of active COVID-19 cases per state as of July 17 (this comes from indiacovid19.github.io , which is periodically archiving the data from India's Ministry of Health). How to configure and style base maps for Choropleths and Bubble Maps. Figure 4.16 demonstrates a tilegram of U.S. Population in 2016 exported directly from Pitch’s free web service. Create choropleth map chart in plotly dash. Figure 4.4 demonstrates using plot_geo() in conjunction with add_markers() and add_segments() to visualize flight paths within the United States. Furthermore, all the scatter-based layers we learned about in Section 3 work as you’d expect it to with plot_ly().12 For example, Figure 4.1 uses plot_mapbox() and add_markers() to create a bubble chart: FIGURE 4.1: A mapbox powered bubble chart showing the population of various cities in Canada. Plotting polygons on mapbox with plotly. 1.1 Connection Map Depicting Flights from Brazil to All Other Countries. Hot Network Questions Serious alternate form of the Drake Equation, or graffiti? It also uses the database world.cities from maps to filter the Brazilian cities and plot them on top of the "native" map. A Choropleth Map is a map composed of colored polygons. plotly is a Python library which is used to design graphs, especially interactive graphs. The integrated approach is convenient if you need a quick map and don’t necessarily need sophisticated representations of geo-spatial objects. “Evaluating Cartogram Effectiveness.” IEEE Trans Vis Comput Graph. For information, there are 2 ways of animating maps with Plotly and Dash : Create a Plotly animated map with multiple frames (Explained below) Create a single Plotly map with updatable trace, updated through a dash callback, monitored by a time slider. ... becomes much more informative and enhanced using plotly … FIGURE 4.2: Zooming in on earth satellite imagery using plot_mapbox(). Here is a short tutorial on how to create an animated world map timeline using plotly.express choropleth. Heat Maps are extremely versatile and efficient in drawing attention to trends, and it’s for these reasons they have become increasingly popular within the analytics community. Google Maps does one thing and it does it well. It is based on the JavaScript library D3.js. The available projections are 'equirectangular', 'mercator', 'orthographic', 'natural earth', 'kavrayskiy7', 'miller', 'robinson', 'eckert4', 'azimuthal equal area', 'azimuthal equidistant', 'conic equal area', 'conic conformal', 'conic equidistant', 'gnomonic', 'stereographic', 'mollweide', 'hammer', 'transverse mercator', 'albers usa', 'winkel tripel', 'aitoff' and 'sinusoidal'. Mullen, Lincoln A., and Jordan Bratt. d3heatmap: a package that uses the same syntax as the base R heatmap() function to make interactive version. Another important feature for maps that may require you to split multiple polygons into multiple traces is the ability to display a different hover-on-fill for each polygon.
