Fork of Points on a Map
This example shows a world map with points for cities, using a natural Earth projection and graticules for geographic context. The visualization layers country land masses and interiors from World Atlas TopoJSON, with semi-transparent circles positioned via `d3.geoNaturalEarth1` and `d3.geoPath`. City data comes from a CSV loaded through `d3.csv`, and the React-based component structure uses hooks like `useWorldAtlas` and `useCities` to manage asynchronous data fetching.
