This example shows an interactive world map with zoom and pan capabilities. The map renders countries as light green SVG paths with indigo borders on a sky-blue sphere background, and countries turn maroon when hovered. The visualization uses D3 v5’s `geoEquirectangular` projection with `geoPath` to draw geographic features, and `zoom` for user interaction. TopoJSON is used to convert world-atlas country data into GeoJSON features.
