Chapter 3. Creating Heatmaps and Choropleth Maps

In the first two chapters, you learned how to make a map and add points, lines, polygons, and even GeoJSON. Now, you will use these skills to create two types of thematic maps: heatmaps and choropleth maps. These maps show you concentrations of points or statistical variables using two different styles of representations.

In this chapter, we will cover the following topics:

What is a heatmap?
How do I create a heatmap?
What is a choropleth map?
How do I create a choropleth map?
