{"version":"1.0","type":"rich","title":"v4 - Boston Crash Map","description":"This visualization displays a geographic map of Boston using hardcoded GeoJSON data of the Roslindale neighborhood, rendered with a Mercator projection via `d3.geoPath`. Crash records from the Boston Crash Dataset, including time, location, and mode type, are plotted as points on the map. The code imports CSV data directly and uses `d3.select` to set up the SVG container, with a projection centered on Boston's coordinates. This version focuses on integrating the neighborhood boundary geometry with the crash data for spatial analysis.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9fbaa22584fc4b5193ab9c3651a8b1d7?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
