{"version":"1.0","type":"rich","title":"Sized Points on a Map","description":"A world map displays cities with populations over 50,000 as semi-transparent teal points, sized proportionally to population using a square-root scale. The visualization uses d3.geoNaturalEarth1 and d3.geoPath to render landmasses, graticules, and sphere geometry from World Atlas TopoJSON, while city coordinates are projected from a Simplemaps CSV. React components manage the asynchronous data loading via d3.csv and d3.json, with SVG circles positioned by the projection and radii mapped from the scale.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e0e6991e9c6f4a5caca7bee0b18e5a9f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
