This fork of a choropleth map colors countries by their economy classification using an ordinal color scale derived from d3.scaleOrdinal and d3.schemeSpectral. It renders geographic boundaries with d3.geoPath and a Natural Earth projection, and includes an interactive color legend built with custom D3 selections. The map supports zooming via d3.zoom, and country tooltips display name and economic group. Data comes from the World Atlas TopoJSON and TSV files, loaded with d3.json and d3.tsv, with hover states highlighting countries in red.
