SilverTrack is a telemetry analysis application for racing cars that uses the Visiblox Charts component.
It plots various telemetry data about the car on the track such as brake depression, RPM, speed, and many more. Moving the cursor along the XAxis of the chart, will display more information about the car on the widgets. Use the "play" button to simulate a lap of the track or add further charts to plot more attributes simultaneously.
