{"version":"1.0","type":"rich","title":"Fork of Sized Points on a Map","description":"A world map displays cities with populations over 50,000, each represented by a semi-transparent circle whose radius is scaled by population using d3.scaleSqrt. The map uses d3.geoNaturalEarth1 and d3.geoPath to render land, graticules, and country boundaries from World Atlas TopoJSON, with data sourced from Simplemaps. React components manage state and rendering, while D3 loads the data via csv and json requests.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8a74d68a72e14c7b8c7e7a3c385ec9d4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
