A world map renders landmasses in teal on a light gray sphere, with graticule lines and country borders overlaid. The visualization uses an orthographic projection via `d3.geoOrthographic` and draws geographic features with `d3.geoPath`. The React component fetches world-atlas TopoJSON data through `d3.json`, converting it to GeoJSON with `topojson.feature` and `topojson.mesh`. Styling is applied through SVG classes, showing a clean, static globe view.
