A rotating orthographic globe displays country boundaries and graticules, with land masses that change color on hover. The visualization uses D3 v5’s `geoOrthographic`, `geoPath`, and `geoGraticule` with a timer to continuously adjust the projection rotation. World map data comes from the World Atlas TopoJSON, while country names are loaded from a TSV file. Zooming is enabled via D3’s `zoom` behavior, and all rendering uses SVG paths.
