{"version":"1.0","type":"rich","title":"Fork of Sized Points on a Map","description":"A map visualization plots world cities with populations exceeding 50,000 as sized points, using a square-root scale to encode population via circle radius. The map uses `geoNaturalEarth1` projection with `geoPath` for land, graticules, and country interiors. City data comes from Simplemaps’ World Cities Database, rendered in React with SVG circles. The visualization is built with d3.v5, featuring a clean, light-styled map with semi-transparent teal circles showing population distribution globally.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/82e2a3b0f1c6476faef0be21b92f2c15?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
