{"version":"1.0","type":"rich","title":"Basketball Court","description":"A world map displays cities with populations exceeding 50,000 as semitransparent circles, sized by population using a square root scale. The visualization uses a Natural Earth projection via `d3.geoNaturalEarth1` and `d3.geoPath`, with landmasses, country interiors, and graticules rendered as SVG paths. City coordinates are projected from latitude and longitude, with circle radii scaled by `d3.scaleSqrt`. Data comes from the Simplemaps World Cities Database and World Atlas TopoJSON, rendered through a React component structure.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/20834c289a9046868c55b0e20c42207e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
