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 maps ACME restaurant franchise locations across the United States with single-select interactivity. A linear color scale shades each state by the number of restaurants it contains, and HTML tooltips summarize the count on hover. Selecting a state populates a side panel with a list of restaurant names, addresses, and website links, plus franchise contact information for states with no locations yet.
