A rotating orthographic globe displays country-level data values, with landmasses rendered in sky blue and hover states highlighted in dark blue. Using D3 v5 with `d3.geoOrthographic` and `d3.geoPath`, the projection rotates continuously via `d3.timer`, while a graticule overlays the sphere. The visualization loads world topology from TopoJSON and country names from a CSV file, with zoom support via `d3.zoom`.
