Fork of World Cities
This map visualizes the locations of cities worldwide using a Natural Earth projection. The visualization displays each city as a small point, with country boundaries in light gray and a graticule overlay. Built with d3-geo, the code uses `geoNaturalEarth1` for projection, `geoPath` for rendering country outlines, and `geoGraticule` for the coordinate grid. City coordinates from a CSV dataset are projected and plotted as circles, while geographic data comes from the visionscarto-world-atlas TopoJSON file. The visualization asynchronously loads both datasets before rendering.
