{"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 teal circles whose radii are scaled linearly by population. The visualization uses d3.geoNaturalEarth1 for projection, d3.geoPath to render landmasses and country borders, and d3.geoGraticule for background grid lines. React manages the component state, with d3.csv fetching city data from Simplemaps and d3.json loading world-atlas TopoJSON. Circles are sized via d3.scaleLinear, capped at a 15-pixel radius.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/32b619d754114701a312684a54477999?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
