This visualization displays world cities with populations exceeding 50,000 as sized points on a natural Earth projection. Circle radii encode population using a square root scale, with data sourced from the Simplemaps World Cities Database. The map renders via React and SVG, using d3.geoNaturalEarth1, d3.geoPath, and d3.geoGraticule to draw country boundaries and graticules, while TopoJSON provides land and interior mesh geometry.
