This example displays a world map using the Natural Earth projection, showing landmasses in teal with country borders and graticules overlaid on a light gray sphere. The visualization fetches geographic data from the world-atlas TopoJSON dataset and converts it to GeoJSON using topojson’s `feature` and `mesh` functions. It renders with React and D3 v7, applying `geoNaturalEarth1`, `geoPath`, and `geoGraticule` to draw the map and its decorative overlays in SVG.
