This example displays a choropleth-style world map rendered as an SVG, with countries shown in a light color against an olive-green sphere background. The visualization uses D3 v5's `geoEquirectangular` projection and `geoPath` to generate the map geometry from TopoJSON data loaded from the world-atlas dataset. Country boundaries are drawn as individual path elements, and hovering highlights the selected country in cyan, using CSS transitions on the fill property. The implementation leverages D3 selections and data joins to bind country features to paths, with a static projection of the globe.
