{"version":"1.0","type":"rich","title":"Opo Tx Data Map","description":"A map of the United States shows circles sized by the number of opioid treatment centers in each city, using a square-root scale. The geographic boundaries come from the US Atlas TopoJSON, while city coordinates are loaded from a CSV. The visualization uses `d3.geoAlbersUsa` and `d3.geoPath` to render state paths, and `d3.scaleSqrt` to map center counts to circle radii, all drawn in SVG within a React component.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a5d68d5919fa44038005ee536e90cb08?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
