This choropleth map colors world countries by their economy category using an ordinal color scale with a spectral scheme. The visualization supports zooming and panning through d3.zoom, while d3.geoNaturalEarth1 and d3.geoPath render the geographic features from TopoJSON world-atlas data joined with TSV country metadata. Countries display a tooltip with their name and economy value on hover, and a custom color legend built with SVG circles and text shows the category mapping.
