This example visualizes world geography using an equal-area natural Earth projection, displaying landmasses in teal against a gray sphere with subtle graticule lines. The map also renders interior boundaries between countries as fine strokes. Built with React and D3, it pulls GeoJSON topology from the `world-atlas` package, applies D3’s `geoNaturalEarth1` projection and `geoPath` for SVG rendering, and uses `topojson.feature` and `topojson.mesh` to prepare the land and interior line data.
