{"version":"1.0","type":"rich","title":"Fork of Fork of Fork of D3 world map example with TopoJSON to GeoJSON and circular indicators","description":"This example displays a U.S. map with circular indicators, initially showing population-based circles over state boundaries. It converts TopoJSON to GeoJSON using `feature` and `mesh` from `topojson`, while `d3.geoPath` renders the SVG shapes. React hooks manage asynchronous data loading from a CDN via `d3.json`. The visualization uses `d3.scaleLinear` and `d3.scaleSqrt` to size and color the circles, though the render function currently outputs an empty SVG.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1e5e1cc8e97a4743b71af0174e75e12d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
