{"version":"1.0","type":"rich","title":"v8 - Boston Crash Map","description":"This map visualizes Boston crash data from data.boston.gov, displaying incidents as colored points based on crash type: red for motor vehicle, blue for pedestrian, and green for bicycle. Users can toggle crash types on and off via interactive checkboxes in the legend. The visualization uses d3.geoPath with a geoMercator projection to render Boston neighborhood boundaries from GeoJSON, and positions crash points from CSV data using the same projection system.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/90ca12ab39044cd2b0d09f000b2093ae?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
