Forked from Points on a Map

This example displays a world map with circles marking cities whose populations exceed 50,000, using data from Simplemaps. The visualization renders geographic features with d3.geoPath and geoNaturalEarth1, including land masses, graticules, and country interiors. City coordinates are projected onto the SVG using the same projection, with semi-transparent circles indicating locations. The map is built with React hooks, d3.v5, and TopoJSON for world atlas data.

A world map showing cities with population greater than 50,000. City data from Simplemaps: World Cities Database.
