{"version":"1.0","type":"rich","title":"Assignment2.2_PieChart","description":"This map of Brooklyn libraries plots each branch as a circle over a geographic map. The visualization uses a Mercator projection via `d3.geoPath` to render the borough’s shape, then positions the library points by parsing latitude and longitude from the CSV. Each point is colored orange and includes a hover tooltip that displays the library’s name, phone number, and accessibility features. The map is built with D3.v7, with map GeoJSON from a public GitHub repository and location data from the Brooklyn Public Library’s CSV.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/cd50297f2b3441dfa92e77856e4bf3b9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
