{"version":"1.0","type":"rich","title":"Points on a Map","description":"A map of the world displays cities with populations over 50,000 as small translucent dots. The visualization uses a React component with D3’s `geoNaturalEarth1` projection and `geoPath` to render country boundaries, graticules, and the sphere outline. City coordinates are projected from latitude and longitude, with data loaded via `d3.csv` from the Simplemaps World Cities Database, while land and interior borders come from TopoJSON in the World Atlas TopoJSON dataset.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/59dd011491bc4542b7f7ff430c7defb2?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
