Sized Points on a Map
✓ Published0🌍 Public
A world map displays cities with populations over 50,000, with each city shown as a semi-transparent circle whose radius is proportional to population via a square-root scale. The map uses a natural Earth projection and includes graticules, country land masses, and interior boundaries. The visualization is built with React and D3, using `d3.geoNaturalEarth1` and `d3.geoPath` for rendering the map, `d3.scaleSqrt` for the circle sizes, and data loaded from a Simplemaps world cities CSV.
