This example renders a world map using React and D3 v5, displaying landmasses in yellow with country borders outlined in dark green on a sky-blue sphere. It uses the `geoNaturalEarth1` projection with `geoPath` to draw the land, graticules, and interior country boundaries from the `world-atlas` TopoJSON dataset. The `useData` hook fetches and processes the TopoJSON features and mesh, while React components structure the final SVG output.
