This visualization displays a world map rendered as SVG, with landmasses filled in teal and country borders drawn as thin interior lines atop a light gray sphere with graticule gridlines. It uses d3.geoNaturalEarth1 projection with d3.geoPath and d3.geoGraticule to generate the geographic shapes, while topojson’s feature and mesh methods extract land polygons and country boundaries from the world-atlas TopoJSON source. React manages the component structure, with data loaded asynchronously via d3.json.
