Using Processing language to visually represent XML. How do I draw an ellipse at each point the data ends/breaks?
===

I'm involved in a research project analysing how (if at all) architecture affects people's paths as they move around locations. So far we have used OpenCV Blob-tracker to successfully produce XML file data mapping the blobs as they move.
What I would like to do now, is draw an ellipse at each point the data begins and ends (to represent each person's start and end point).
Any help on reaching this conclusion would be most welcome.
