A world map displays cities with populations over 50,000 as semi-transparent red circles, with circle size scaled by population using a square-root scale. The map uses a natural Earth projection via `d3.geoNaturalEarth1` and `d3.geoPath`, rendering landmasses, country interiors, and graticules from World Atlas TopoJSON data. City coordinates and populations come from a Simplemaps CSV, processed with React hooks and D3’s `csv` loader, and the visualization is built with React and SVG.
