I am not going to squint at this to make out the supposed path:
Suggestion: Have a single toggle button that toggles an animation that draws out the trail one point at a time (with the lines for all points drawn thus far showing as well). Works well with 20 sessions. You can put an arbitary amount of time into making this look neat with various scaling/bounce/color shifts of points, maybe not the focus of the platform though.
If the toggle is off, then just show the current static render.
