This visualization displays a world map highlighting estimated population figures for each country, with hover interactions that reveal the country name and population in a formatted label. The map uses a natural Earth projection rendered as SVG paths, and supports zooming and panning through d3.zoom. Population data comes from the world-atlas TopoJSON and TSV files, which are loaded via Promise.all. Country polygons are generated with d3.geoPath, and tooltips are implemented using SVG title elements.
