This interactive world map visualization uses a D3.js geo projection to render countries from a TopoJSON dataset. The map is drawn as SVG paths using the `d3.geoEquirectangular` projection and `d3.geoPath`, with pan and zoom enabled through the `d3.zoom` API. Countries appear in light green with indigo borders, and hovering changes their fill to maroon. The background sphere is filled with sky blue, and the map loads geographic boundary data from the world-atlas package.
