This example shows a world map rendered with an equal-earth projection, with countries filled in teal against a light gray sphere. It uses D3’s `geoEqualEarth` for projection, `geoPath` to generate SVG paths from TopoJSON data loaded via `topojson.feature` from the world-atlas dataset. The visualization is built as a React component, where a `Marks` component renders each country path, and a loading state displays until the asynchronous data fetch completes.
