{"version":"1.0","type":"rich","title":"Assignment2.2_GeoMapGraph","description":"This example maps the locations of Brooklyn Public Library branches as orange points over a green choropleth of Brooklyn neighborhoods. The map uses a D3 geoMercator projection and d3.geoPath to render GeoJSON boundaries, while library coordinates are loaded from a CSV and drawn as SVG circles. Hovering over a point enlarges it and displays a tooltip with the branch name, phone number, and accessibility status. The visualization is built with D3 v7 and renders entirely as SVG.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c0c8a451912a47f9b406622c2d6b22fe?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
