This visualization displays a world map using a Natural Earth projection, rendered as SVG paths. It shows landmasses in teal, graticule lines in light gray, and country borders highlighted with a darker teal stroke. The map is generated from TopoJSON data (world-atlas countries-50m.json) loaded with d3.json, then converted to GeoJSON using topojson.feature and topojson.mesh. The React component structure relies on hooks (useState, useEffect) to fetch and process the data, while d3.geoNaturalEarth1 and d3.geoPath handle the projection and path generation.
