{"version":"1.0","type":"rich","title":"Points on a map","description":"A geographic scatter plot displays city populations using a square-root size scale for circles overlaid on a landmass map. The visualization uses React with D3’s `geoMercator` projection and `geoPath` to render country boundaries, while the `scaleSqrt` function scales circle radii by population data. The map data comes from TopoJSON, and the city dataset originates from the Data Canvas Sense Your City dataset.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d8c5e38b50284e3592b09c3ac8b9d25a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
