{"version":"1.0","type":"rich","title":"Fork of Sized Points on a Map","description":"This example visualizes a world map with circles sized by city population, focusing on cities with populations exceeding 50,000. The map uses a Natural Earth projection rendered with `geoNaturalEarth1` and `geoPath`, while city points are positioned via the projection and scaled using `scaleSqrt` for their radius. Data is sourced from Simplemaps and world-atlas TopoJSON, with graticules and polished land boundaries. The visualization is built with React, leveraging `d3.csv` for data loading and `topojson.mesh` for interior boundaries.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e76431be7d594dd1b936f92e58b88f4d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
