A three-dimensional world map rotates continuously as countries are colored according to population data sourced from the file's embedded constants. The orthographic projection and graticule lines are drawn with `d3.geoPath` and `d3.geoGraticule`, while the globe's spin is driven by a recursive `requestAnimationFrame` loop. User interaction via dragging is contemplated, though the current implementation only auto-rotates the view. Topological data is fetched from a remote atlas and converted using `topojson-client`.
