Fork of world map w/ cities & countries pop!
This visualization displays a world map with cities exceeding 50,000 population and country-level population data. Cities appear as scaled circles based on population, while countries vary in opacity according to their population figures. The map uses React with d3-geo-projection’s `geoNaturalEarth1` projection and `geoPath` for rendering. City data comes from Simplemaps, country boundaries from World Atlas TopoJSON, and population values from a UN 2019 dataset. Additional geographic lines and graticules enhance the map’s spatial context.
