Complex process. The first one is not the simplest, it is -essentially- a proof of concept: Process can be complex. demoARVSpaghetti


Linear process. The second one is the beginning of a long story: how to visualize the activity of students (linear process). sci_1


Data that are not student’s traces of interaction. The third one is an example of possible use of UnderTracks for another purpose: how to find and visualize differences between judges’ evaluation. hysteresisLog


A new idea. Different visualization to find the good one. ife


Linear process becomes a star. It’s a merge of the linear process and of the previous process. copex2
