{"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 circles sized proportionally to population using a square-root scale. The visualization uses d3.geoNaturalEarth1 projection, d3.geoPath, graticules, and country boundaries from World Atlas TopoJSON, with city data from a Simplemaps CSV. React manages state and rendering, while d3.scaleSqrt maps population values to circle radii. The SVG output includes styled landmasses, sphere background, and interior borders.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d99e395af3294c65b4fd3b7174c32a91?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
