Points on a map
This visualization displays a world map with city points scaled by population. Country outlines and graticules are rendered using d3.geoPath and the geoNaturalEarth1 projection, with city populations mapped to point radii via a d3.scaleSqrt. Data comes from a CSV of world cities and TopoJSON world atlas features, rendered as SVG within a React application.
