{"version":"1.0","type":"rich","title":"v5 - Boston Crash Map","description":"A geographic map of Boston displays crash locations as points against a basemap of neighborhood boundaries. The visualization shows the spatial distribution of incidents across the city, with individual crashes differentiated by mode type—motor vehicle, pedestrian, or bicycle—using a Mercator projection. Built with D3.js, it uses `geoMercator` and `geoPath` to render the neighborhoods, while crash coordinates from a Boston Crash Dataset are projected as points.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/81efeac5f6a84e9ab25932dbb4334916?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
