A spinning globe rendered with an orthographic projection animates its rotation around the y-axis. The visualization displays country boundaries and a graticule over a dark background, with a visible sphere outline. The code uses d3-geo’s `geoOrthographic`, `geoPath`, and `geoGraticule` functions to draw the map, and requests animation frames via `requestAnimationFrame` to update the projection’s `rotate` property. World country data comes from the visionscarto-world-atlas TopoJSON file processed with `topojson-client`.
