This animated visualization shows a spinning orthographic globe with country boundaries and a graticule grid, rotating continuously around its vertical axis. The map renders world geography from a TopoJSON dataset fetched from unpkg.com, using D3’s `geoOrthographic`, `geoPath`, and `geoGraticule` to project and draw the sphere, outline, and countries. Animation is driven by `requestAnimationFrame`, updating the rotation state to decrement the longitude each frame, which re-renders the projection. The code manages state transitions and cleanup for hot reloading.
