This fork of a choropleth map visualizes World Bank GDP per capita (PPP, current international dollars) for 2020 across countries. The map uses a natural Earth projection with a graticule and country outlines, coloring each nation on a quantile-based YlGnBu color scale from d3.scaleQuantile and d3.schemeYlGnBu, with missing data rendered in gray. It loads country geometries via topojson-client from a 110m atlas, fetches the CSV dataset, and renders the choropleth using d3.geoPath from the d3 library.
