This example shows an interactive world map rendered with SVG, where hovering highlights countries in red and clicking logs the selected country's ID. The visualization uses D3 v5's `geoPath` and `geoNaturalEarth1` projections to draw geographic boundaries, and the `zoom` interaction module enables pan and zoom transformations. Country names come from a TSV file loaded from the world-atlas package, while geometric data is parsed from TopoJSON using the topojson library.
