This choropleth map displays countries colored by economic classification, sourced from the world-atlas dataset. Built with React and d3.v5, it uses d3.geoNaturalEarth1 and d3.geoPath to project and render GeoJSON features. A color legend, created with a custom d3.scaleOrdinal component, maps categories to a spectral scheme. D3 zoom interactions allow panning and scaling, while CSS hover states highlight individual countries.
