This interactive world map displays countries in light green with black borders, highlighting them in red on hover. It uses a geographic projection to render the map and provides zooming capabilities through the `d3.zoom` API, which applies a transformation to the map group on zoom events. Country boundaries are drawn using `d3.geoPath` with the `geoNaturalEarth1` projection, and country names are retrieved from a TSV file while geometry comes from a TopoJSON dataset, processed via the `topojson.feature` function.
