Choropleth (GIS)
Native choropleth maps for geography, demography, and epidemiology. Ships with a compact built-in atlas of world countries (ISO-3166 alpha-2) as a stylised hex-tile grid — no TopoJSON download required. Provide values per country code and the engine colour-scales them automatically. Bonus: a US states map (USPS codes) for state-level dashboards. Bigger atlas / SVG-accurate borders coming in a follow-up.

Annual-average unemployment rate for all 50 states on the US hex atlas, from 1.9% in SD to 5.6% in NV: the Plains and northern New England are tight labour markets, while Nevada, California and the industrial Midwest run highest. A sequential ramp suits a rate with no meaningful midpoint. Illustrative values.
