{"version":"1.0","type":"rich","title":"Fork of Points on a Map","description":"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.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/daf75b5bf2c24790bfdba172e9174c7b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
