This example presents an interactive world map as a rotating orthographic globe. The visualization loads geographic boundary data from a JSON file and renders it as SVG paths, continuously adjusting the map’s rotation with a timer. The animation rotates the projection along its horizontal axis using `projection.rotate()`, while a tilting offset adjusts the vertical perspective. The map uses `d3.geoOrthographic`, `d3.geoPath`, and `d3.geoProjection` to create the spherical effect, and the countries are filled with a solid green color.
