This example displays a world map with country boundaries and graticules, rendered using SVG. It uses React to manage the component structure while D3’s `geoNaturalEarth1` projection and `geoPath` draw the sphere, landmasses, and interior borders. The data comes from World Atlas TopoJSON, loaded via `useData` and processed with `topojson.feature` and `topojson.mesh`. A muted color palette highlights the land and sphere, with subtle strokes for graticules and interiors, producing a polished cartographic style.
