{"version":"1.0","type":"rich","title":"Fork of Sized Points on a Map","description":"This example presents a world map with a point for every city whose population exceeds 50,000, using a square-root scale to size each circle proportionally to its population. The map is rendered with SVG using React and D3 v5, employing `geoNaturalEarth1` for the projection and `geoPath` for drawing land, interiors, and graticules. City data comes from the Simplemaps World Cities Database, while country boundaries derive from World Atlas TopoJSON, with circles styled in teal at partial opacity.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/fa5b256359c74dba8eb5e459bab0438c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
