This example shows an interactive orthographic globe rendered with SVG, where users can drag to rotate the Earth and see country boundaries and graticule lines. The code uses `d3.geoOrthographic` for projection and `d3.geoPath` to draw geographic features from TopoJSON data sourced from the world-atlas package. Drag events update the projection’s rotation, while zoom is handled via `d3.zoom`. Country names are loaded from a TSV file and displayed as tooltips using SVG `<title>` elements.
