This choropleth map colors countries by their United Nations region using an ordinal spectral color scale. The visualization renders geographic boundaries with D3’s geoNaturalEarth1 projection and geoPath, while loading country shapes and metadata from the world-atlas TopoJSON and TSV sources. A custom color legend explains the region-to-color mapping, and hovering highlights individual nations. The map supports zooming and panning through D3’s zoom event handler, with the sphere background filled in blue.
