This example demonstrates a geographic visualization of the world with orthographic projection, showing countries as interactive yellow shapes that turn red on hover. The map uses D3.js v5 with the `geoOrthographic` and `geoPath` functions to render country boundaries from the world-atlas TopoJSON and TSV data files, which provide geometry and country names. Interaction includes a zoom feature that transforms the map projection and hover effects that change fill color, with attributes managed through D3’s selection and event handling.
