This world map visualization displays the Earth using a natural Earth projection, with landmasses filled in teal and graticules shown as gray lines. Country borders are rendered as cyan strokes using topological data from the world-atlas dataset. The visualization is built with React for component structure and D3's geoNaturalEarth1 projection, geoPath, and geoGraticule functions for geographic rendering. The code also uses TopoJSON's feature and mesh methods to extract land polygons and interior boundaries from the topology, with SVG paths styled through CSS.
