This choropleth map visualizes 2024 estimated country populations, coloring nations from light yellow to dark red on a Natural Earth projection to show relative population sizes. The visualization uses d3.geoNaturalEarth1 for map projection and d3.geoPath to render country boundaries from TopoJSON data loaded via d3.json and converted with the `feature` function. Population values are mapped to colors using d3.scaleSequential with an interpolateYlOrRd color scheme, while hover tooltips display each country’s name and population using SVG `<title>` elements.
