World agglomerations — UN WUP 2025 estimates
The world's 100 largest metropolitan areas by agglomeration population (not the administrative city alone) — a points layer, proportional circles, with automatic clustering on zoom-out.
United Nations, World Urbanization Prospects 2025 — 2025 estimates.
Circle size encodes agglomeration population.
