This interactive world map displays global countries with a three-dimensional orthographic projection, allowing users to drag the globe to rotate it and click individual countries to switch between projections. The visualization uses D3.js with `d3.geoPath` and `d3.geoProjection` for rendering, TopoJSON for country boundaries, and world-atlas data. A graticule overlay shows latitude and longitude lines, while a `d3.drag` handler enables rotation and `d3.zoom` supports scaling. Country names are linked via TSV data, and hover effects highlight selected regions.
