{"version":"1.0","type":"rich","title":"Fork of Points on a Map","description":"This example renders a world map using a Natural Earth projection, showing cities with populations over 50,000 as semi-transparent points. The visualization loads geographic boundaries from World Atlas TopoJSON and city data from Simplemaps, then draws them with SVG paths and circles via `d3.geoNaturalEarth1`, `d3.geoPath`, and `d3.geoGraticule`. The React components manage data fetching through custom hooks, while D3’s `csv` and `json` methods load the datasets.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/039ed8b45de64d758eff3d1b92bddd15?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
