A world map visualization displays country boundaries and graticules, styled with a teal landmass and light sphere. The map uses d3.geoPath with a geoNaturalEarth1 projection to render land features and a wireframe mesh that connects country interiors. It sources World Atlas TopoJSON data, processed with topojson.feature and topojson.mesh, and is built in React with SVG rendering. The visualization is polished with CSS styling for the land, sphere, and graticule paths.
