This example shows an interactive world map rendered as SVG, where each country is colored light green and turns red on hover, with a dark blue sphere backdrop. Built with D3.js v5 and TopoJSON, it uses `d3.geoNaturalEarth1` for projection and `d3.geoPath` to draw country boundaries from the World Atlas 50m dataset. Zoom and pan are enabled via `d3.zoom`, while country names are loaded from a TSV file and attached as SVG title tooltips.
