This example renders a continuously rotating orthographic globe using D3's `geoOrthographic` projection and `geoPath` to draw landmasses and a graticule. World map data comes from the VisionsCarto World Atlas as TopoJSON, processed with `topojson-client`. The animation updates the projection's rotation each frame via `requestAnimationFrame`, modifying state and redrawing the spherical outline and coastline in a dark, teal color scheme.
