This map shows the world's countries as tan polygons against a light blue sphere, with hover states that turn the countries brown. The visualization is built with D3 v5 and TopoJSON, using `d3.geoEquirectangular` and `d3.geoPath` to generate the projected SVG paths. Country boundary data comes from the `world-atlas` countries-110m.json file, and the rendering is entirely SVG-based with a CSS-driven hover effect on the `.country` class.
