{"version":"1.0","type":"rich","title":"Fork of Polished World Map","description":"This visualization displays Major League Baseball stadiums on a polished map of the United States, with circles sized according to stadium capacity and colored by division. Built with React and D3 v5, it uses `d3.geoAlbersUsa` projection and `d3.geoPath` to render state boundaries and interiors from US Atlas TopoJSON data. The map loads stadium coordinates, capacities, and divisions from a CSV file, applying `d3.scaleSqrt` for circle sizing. Interactive dropdown menus allow filtering by division, supported by React state management and custom axis and legend components.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/143a861662a94d3aa4a6f8cd98d07682?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
