This world population choropleth map uses a natural Earth projection to visualize population data across countries. The map is rendered as SVG paths, with each country filled using a sequential blue color scale that maps population values from low to high. Built with D3.js v7, the visualization loads GeoJSON country boundaries via the world-atlas package and topojson-client, then joins them with a CSV dataset of world population figures. The `d3.geoPath` and `d3.geoNaturalEarth1` APIs handle the geographic projection and path generation.
