There is not much to this graphic, other than the fact that it was made in GeoGebra (using a clip-art graphic from here).
There is, however, a lot of mathematics involved in its creation. This diagram is not intended to teach, show, or explain anything. The creation of this diagram (similar to yesterday's) could make for a great lesson involving geometry, algebra, systematic thinking in general, and target-based thinking. For this diagram, I will withhold my source so that, if you just want to copy it, you really have to search it out.
