This map visualizes world landmasses and country borders using a Natural Earth projection. The React-based application loads GeoJSON data from the World Atlas TopoJSON file, converting it with `topojson.feature` and `topojson.mesh`. Using D3’s `geoNaturalEarth1` projection and `geoPath`, the SVG rendering displays land in teal, graticules in light gray, and country boundaries with a subtle stroke. The sphere outline and graticule grid provide geographic context, while the Poppins font styles the interface.
