{"version":"1.0","type":"rich","title":"Fork of Sized Points on a Map","description":"A world map displays cities with populations over 50,000, with circle size scaled by population using a square-root scale from d3-scale. The visualization renders geographic features—landmasses, country interiors, the sphere, and graticules—via d3.geoNaturalEarth1 and d3.geoPath in an SVG. City coordinates are projected from latitude and longitude, while data comes from a CSV of world cities and the World Atlas TopoJSON, all styled with translucent teal circles.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/35b06b947c76438bbc998812027d674d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
