Geogebra in a Panel Pane. Anybody want to play? There is a Javascript API

Hello @Marc
that would be real overkill compared to what I had in mind:
I’ll get around to just add a button or two that execute javascript:
hide/show editing toolbars, load another example.

The use case I have: I was putting together a linear transformations lecture.
(Hence my other post about arrows: that figure was done with julia Plot…)
