A world map displays cities with populations exceeding 50,000 as semi-transparent teal circles, sized proportionally to population using a square root scale. The visualization renders geographic context—landmasses, country interiors, graticules, and a sphere—using d3.geoNaturalEarth1 and d3.geoPath, with city data loaded via d3.csv from the Simplemaps World Cities Database and country boundaries from TopoJSON. React manages the component state, while d3-scale and d3-geo handle projection and sizing.
