Doing the plotting should not be a problem - the interesting bits will be
to associate the data with the plot, so that you can click to "drill down"
to see the speed, etc.

Or maybe you should do two things at once - show the position of the car
on the track, and a running graph of the variables of interest.

In a sense, plotting on a canvas is a fairly simple co ordinate transformation
problem.
