TEST
An interactive orthographic globe displays graticule lines, a red rectangular arc region, and a sphere outline, with a hidden world map loaded for future rendering. Users drag to rotate the projection via `d3.drag`, adjusting the rotation with `projection.rotate`, and zoom using `d3.zoom` to transform the SVG group. The visualization uses `d3.geoOrthographic`, `d3.geoPath`, and `d3.geoGraticule`, fetching TopoJSON from the world-atlas package, while styling SVG paths with CSS classes for the sphere, graticule, and rectangle.
