{"version":"1.0","type":"rich","title":"Fork of Sized Points on a Map","description":"A world map displays cities with populations over 50,000 as semi-transparent teal circles, sized using a square-root scale that maps population to radius. The map includes natural Earth landmasses with graticules and country interiors, styled in muted grays. The visualization is built with React, using d3's `geoNaturalEarth1` projection and `geoPath` for rendering, while city data comes from Simplemaps and country boundaries from the World Atlas TopoJSON.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/fe9f61c8bff24a65a315e919f734cbfa?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
