{"version":"1.0","type":"rich","title":"Sized Points on a Map","description":"A world map displays cities with populations exceeding 50,000 as semi-transparent teal circles, sized proportionally to population using a square root scale. The visualization renders geographic context—landmasses, country interiors, graticules, and a sphere—using d3.geoNaturalEarth1 and d3.geoPath, with city data loaded via d3.csv from the Simplemaps World Cities Database and country boundaries from TopoJSON. React manages the component state, while d3-scale and d3-geo handle projection and sizing.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4d42eecbe1fe4e42822ee1d5e09263f6?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
