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 highlights every country where Spanish is an official language on a world map, using ISO alpha-2 codes for geodata matching. Custom HTML tooltips show a contextual description pulled from each data record, while source credits link back to the Wikipedia reference. Zoom controls let users explore the map at closer detail.
Follow the step-by-step Choropleth Map Tutorial to learn how such maps are built. See the Choropleth Map documentation for all configuration options.
