This example displays a map of the world on a dark grey spherical globe with white borders. The globe is rendered using React and SVG, with the d3.geoOrthographic projection and d3.geoPath converting geographic data into SVG paths. Country boundaries are drawn from a TopoJSON file loaded using the d3.json function. A large grey circle provides the globe’s background, while the map features are layered on top with thin white strokes.
