In this chapter, you have taken your map-making skills beyond points, lines, polygons, and GeoJSON to create map visualizations—heatmaps and choropleth maps. You have learned how to use two different plugins to make heatmaps and how to style them for maximum visual effect. You also learned how to make your heatmap interactive and create animations to show the time series data. Choropleth maps did not require plugins. You learned how to style GeoJSON data to make a choropleth map. Lastly, you learned the difference between totals and normalized data.
In the next chapter, you will learn how to create your own markers. You will also learn about several plugins that animate and enhance the markers on your map.
