This interactive world map displays all countries as light green shapes on a blue sphere, highlighting them in red on hover. It renders geographic boundaries using the `d3.geoPath` projection with the `geoNaturalEarth1` projection and supports pan and zoom through the `d3.zoom` API. The map is built from world-atlas TopoJSON and TSV data, which supplies country names via ISO codes, and each shape includes a tooltip showing the country name.
