A choropleth map shades geographic regions by data value, making spatial patterns in quantitative data instantly visible. It is one of the most popular thematic map types for comparing statistics across countries or states.
This sample plots ACME dealership counts across all US states, loaded from a JSON data source. A linear color scale transitions from light gray to blue based on how many dealerships each state has. Custom HTML tooltips display the exact count per state, and clicking any state opens the corresponding Wikipedia article, demonstrating the pointClick event handler for drill-out navigation.
Follow the step-by-step Choropleth Map Tutorial to learn how such maps are built. See the Choropleth Map documentation for all configuration options.
