      Click in the "Region Images" plot and you will see a small circle appear. As you move around in the "Region Images" plot, the preimages of that point are displayed on the "Region Preimages" plot. The grey circles on the "Region Images" plot are the images of the critical points (the "critical values".) Observe how the preimages behave as you get close to the critical values.
