Fork of Points on a Map
This visualization displays a world map with cities whose populations exceed 50,000, sourced from the Simplemaps World Cities Database. The map uses a natural Earth projection, rendered as SVG through React, with country boundaries from the World Atlas TopoJSON. D3's `geoNaturalEarth1` projection, `geoPath`, and `geoGraticule` functions draw the sphere, graticules, and landmasses, while city coordinates are projected and plotted as semi-transparent teal circles. The styling employs muted grays for geographic features, creating a clean backdrop for the city data points.
