This example presents an interactive orthographic world map that automatically rotates over time. The visualization uses D3’s `geoOrthographic` projection and `geoPath` to render continents and graticules as SVG, with country data from the world-atlas TopoJSON and TSV files. Users can zoom and pan the globe via `d3.zoom`, while hovering over landmasses highlights them in yellow. The rotation is driven by a `d3.timer` that continuously updates the projection’s rotation.
