Fork of Choropleth Map with Interactive Filtering
This choropleth map displays global economic classifications by country, with colored regions projected using a natural Earth projection. Users can click legend items to filter the map, highlighting matching countries while dimming others, and can zoom and pan the visualization. The example uses d3.geoPath and d3.geoNaturalEarth1 for map rendering, d3.zoom for interaction, and d3.scaleOrdinal with schemeSpectral for coloring, loading geographic data from the World Atlas TopoJSON dataset alongside TSV metadata.
