This interactive map displays world countries colored by economic status, with tooltips revealing the country name, continent, and broader economic position on hover. Users can click a country to select it, and a zoom interaction allows panning and scaling the projection. Built with D3.js, the visualization uses `d3.geoPath` and `d3.geoEquirectangular` to render geographic features from TopoJSON data, while loading country metadata from a TSV file. The map supports hover highlighting and a separate CSS class for selected countries.
