{"version":"1.0","type":"rich","title":"Opo Cities","description":"The visualization depicts the geographic distribution of \"opo\" cities across the United States, with a dark landmass and circles sized proportionally to the number of centers in each city. Using React with D3 v5, it renders an Albers equal-area projection via `d3.geoPath`, plotting map features from the US Atlas TopoJSON and city coordinates from a CSV file. The circles’ radii are scaled by the square root of the `Centers` attribute, providing a clear comparison of city significance.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b9ff86a27010400b9421c6d810d7670e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
