A polished world map renders country boundaries from World Atlas TopoJSON data, using an orange land fill against a black sphere with light blue interior borders and grey graticules. The visualization uses React to manage state through a custom `useData` hook that fetches and converts topology via `topojson.feature` and `topojson.mesh`. D3's `geoNaturalEarth1` projection and `geoPath` generate the SVG paths for land, sphere, graticules, and country boundaries, displaying a clean, stylized geographic overview.
