This example displays a natural Earth projection of the world, using a flat SVG canvas. Landmasses are filled in teal, while graticules and a light gray sphere background define the map’s frame—the latter including a polygon that traces national interiors. Built with React and D3 v7, it leverages `geoNaturalEarth1` for projection, `geoPath` for rendering geographic features, and `geoGraticule` for the grid. The underlying data is fetched from the `world-atlas` TopoJSON source, with terrain and boundary polygons extracted via `feature` and `mesh` from the `topojson` library.
