This fork of a polished world map uses D3’s `geoNaturalEarth1` projection and `geoPath` to render both country boundaries and graticules over a gray sphere. It loads world topology from the World Atlas TopoJSON via `d3.json`, then converts the land and interior meshes with `topojson.feature` and `topojson.mesh`. React components structure the SVG output, while CSS styles the land in teal and highlights interior borders with a contrasting stroke. The visualization updates asynchronously, displaying a loading prompt until the geographic data arrives.
