I looked at this chart and I only see a bunch of medical terms I don't understand (to be fair I understand approximately 13% of them). I tried to look at the image like those 3-D pictures that confounded William in Mallrats, but I just couldn't see anything. Can a reader explain this to me? I sorta get it, but dumb it down for me. We found it on the 420 Tribune. You can see a bigger picture there.
