This interactive globe displays world countries using an orthographic projection, with a graticule overlay and draggable rotation. Clicking a country switches between projections: selecting the United States triggers a smooth 750ms transition to a Mercator projection, while any other country returns to the orthographic view. The visualization uses `d3.geoPath` for rendering, `d3.drag` for rotation, and `d3.zoom` for panning, with country names resolved from a world-atlas TSV. Data comes from world-atlas TopoJSON, rendered as SVG paths with hover highlighting.
