Choropleth Map
A choropleth map shades geographic regions — countries, states, counties, or NUTS regions — by a data value, so spatial patterns in demographic, economic, or election data jump out immediately.
Mapji ships with built-in boundaries for countries (ADM0), states (ADM1), counties (ADM2), and European NUTS1–3 regions, so you just match your data to region names and pick a color scale. No shapefiles to wrangle.
