This example displays a world map using an equirectangular projection, rendering each country as a pink SVG path with black outlines on a blue sphere. The visualization uses D3 v5 functions `d3.geoEquirectangular` and `d3.geoPath` to project and draw the geography, while TopoJSON’s `feature` method converts country boundaries from the world-atlas TopoJSON file. Hovering over a country turns its fill white, highlighting the selected region.
