Visualizing TFL Accident Data is an interactive mapped visualization of 2015 London traffic accidents. The map uses data from Transport for London and is color coded on the map by the severity of the injury involved.
You can filter the results displayed on the map by the severity of the injuries. When you filter the results the summary statistics in the side panel update to show the type of vehicles involved and the ages of the injured. The London cartogram also updates to show the number of causalities in each borough.
If you select a marker then details of the accidents at that location are displayed on the map. The details include the type of vehicle involved, who was involved (driver or passenger) and their age.
The map itself was created with the Google Maps API with D3.js used to create the scaled map markers and side panel graphs and cartogram.
