This example shows an interactive world map rendered with D3.js, displaying country boundaries and names using SVG. It uses `d3.geoNaturalEarth1` for the projection and `d3.geoPath` to generate the geography from TopoJSON world-atlas data (110m resolution) with country names joined from a TSV file. Countries highlight red on hover, and `d3.zoom` enables pan and zoom interactions on the map.
