✓ Published0🌍 Public
A world map displays cities with populations over 50,000 as semi-transparent circles, sized by population using a square-root scale. The visualization uses React to render SVG marks, with d3.geoNaturalEarth1 and d3.geoPath for the map projection and country boundaries. City data comes from the Simplemaps World Cities Database, and the map includes graticules and interior borders from World Atlas TopoJSON, styled with light gray fills and strokes.
