{"version":"1.0","type":"rich","title":"Sized Points On A Map","description":"This example shows a world map with circles sized by city population, where each city is positioned by its latitude and longitude. The map uses a stereographic projection and includes graticules, land masses, and country borders. React manages the component state while D3’s `csv` loader fetches city data from a GitHub gist, and `scaleSqrt` maps population values to circle radii. The visualization renders in SVG, with semi-transparent blue circles over a light gray map.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/83e8a3e6f74b468fbd12e48fe6b5d89d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
