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 classifies every country by its system of government — from presidential and parliamentary republics to monarchies and single-party states — using multiple filtered choropleth series and a ten-color distinct palette. An interactive legend on the right lets visitors click to isolate a single government type, with custom tooltips and zoom controls for deeper exploration.
Follow the step-by-step Choropleth Map Tutorial to learn how such maps are built. See the Choropleth Map documentation for all configuration options.
