A rotating orthographic globe displays world landmasses and graticule meridians in SVG. The Earth spins continuously via a d3.timer that updates the d3.geoOrthographic projection’s rotation, with d3.geoPath rendering the geographic features from TopoJSON world-atlas data. A hover effect darkens countries, while a static color legend lists continents. Zoom and pan are supported through d3.zoom, with the globe group transformed on user input.
