This interactive globe visualization displays world countries using D3.js with TopoJSON data. It rotates between Mercator, orthographic, and Albers USA projections via click events, while allowing drag-to-rotate and zoom controls. The map renders country boundaries with graticule lines, using `d3.geoPath` for projection and transitions. Country labels appear from a world-atlas TSV dataset, and the sphere animates between projections when clicked.
