This fork of a choropleth map visualizes countries colored by their economy category, with a legend showing the ordinal color scale. The map uses a natural Earth projection and supports zooming and panning via d3.zoom, while hovering highlights a country in red. Data from the World Atlas TopoJSON and TSV files is loaded with d3.json and d3.tsv, processed through topojson.feature, and rendered as SVG paths using d3.geoPath. The legend is built with a custom component using D3 selections.
