This choropleth map visualizes the world’s economies using color-coded countries, with interactive filtering by clicking legend items to highlight specific economic categories. The map uses an Equirectangular projection and supports zooming and panning. Built with D3 v5, it employs `geoPath` and `geoNaturalEarth1` for geographic rendering, while a clickable `colorLegend` toggles opacity and highlights selected regions. Data originates from the World Atlas TopoJSON and TSV files, rendered as SVG elements.
