This visualization displays a world map using SVG paths, with each country rendered as a distinct shape that changes color on mouse hover. It also shows country names and population estimates as tooltip labels. The map uses d3.geoNaturalEarth1 projection and d3.geoPath to draw geographic features from TopoJSON data, while country metadata comes from a TSV file. Interaction is handled through CSS hover effects, with country names and populations loaded from world-atlas and countries.json sources.
