Each point is plotted by longitude and latitude from BPL_Locations.csv, projected with `d3.geoMercator()` and drawn as SVG circles. Hovering a point displays a tooltip with the branch name, phone number, and accessibility tags. The underlying neighborhood boundaries come from Brooklyn GeoJSON, rendered through `d3.geoPath()`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b432abac3a06464880f8256c7fa3cea3?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
