This example renders a natural Earth projection world map using D3’s `geoNaturalEarth1`, `geoPath`, and `geoGraticule` APIs, with React managing the SVG output. Landmasses fill in teal, while graticules and interior boundaries appear as light and darker strokes, respectively. The map’s data comes from the `world-atlas` package, loaded via D3’s JSON fetcher and processed with TopoJSON’s `feature` and `mesh` functions to distinguish country interiors. The visualization presents a clean, stylized globe with a subtle sphere outline and a muted background.
