This interactive SVG map visualizes 2023 world population estimates using a logarithmic color scale, with countries shaded from light yellow to dark blue-green based on population size. Countries lacking data appear in neutral gray, and hovering over any nation reveals a tooltip with its name. Built with D3.js v7 and TopoJSON, the map employs a Natural Earth projection, graticule grid, and sphere background. Population values come from the UN World Population Prospects 2023, keyed by ISO numeric country codes, and the color encoding uses `d3.scaleSequentialLog` with an interpolator for the YlGnBu color scheme.
