{"version":"1.0","type":"rich","title":"v2 - MA Crash Map","description":"This map of Massachusetts shows the geographic distribution of traffic crashes using red dots plotted over the state’s outline. The visualization uses GeoJSON for the state boundary and crash data containing coordinates to place each incident on the map. The code relies on D3 libraries including `d3.geoMercator` for the map projection, `d3.geoPath` to generate the state’s path, and D3’s projection methods to convert crash latitude and longitude into screen coordinates for circle placement. The crash data originates from the Boston Crash Dataset.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7ae09253c93341ae8cc9954694307b84?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
