{"version":"1.0","type":"rich","title":"Boston Crashes","description":"This interactive visualization combines a geographic map of Boston with crash data from the city’s Vision Zero program, plotting each incident as a colored circle based on mode type—red for motor vehicles, blue for pedestrians, and green for bicycles. A toggleable time series chart below aggregates monthly crash counts using `d3.bin` and `timeMonth`, while checkboxes allow filtering by mode to update both views. The map uses `d3.geoMercator` and `d3.geoPath` to render Boston neighborhood boundaries from a GeoJSON file, with crash locations projected via longitude and latitude coordinates.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ba3c1354b56d4045b1b29a942cebd6da?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
