This example shows an interactive world map rendered in SVG using D3 v5, where countries appear in light green against a dark blue spherical background. Users can zoom and pan the map via a d3.zoom handler that applies SVG transforms to the map group. Natural Earth projection is applied through d3.geoNaturalEarth1, with country boundaries drawn via d3.geoPath. Country names come from a TSV file joined to TopoJSON geometry using topojson.feature, and hovering highlights a country in red via a CSS :hover rule.
