This example renders a polished world map using React and D3 v5. It displays landmasses, country interiors, graticules, and the globe sphere, with country boundaries sourced from World Atlas TopoJSON data. The visualization uses d3.geoNaturalEarth1 for projection and d3.geoPath to draw SVG paths for both land features and interior mesh lines. The map is styled with a teal land fill and subtle gray graticules, presenting a clean, refined cartographic aesthetic.
