This example shows a world map rendered as a bright pink sphere with yellow country shapes outlined in green. It uses D3 v5 and TopoJSON to load geographic data from a GitHub-hosted JSON file. The map is drawn in SVG using `d3.geoPath` with the `geoNaturalEarth1` projection, and country boundaries are generated via `feature` from the topojson library. The sphere and countries are styled with CSS classes.
