I don’t think the two pictures are isomorphic. The word “isomorphic” means that it is a bijection that preserves structure from one set to another, but I don’t really see that here beyond a superficial aesthetic similarity. One thing that is isomorphic is mathematical proofs and well-typed computer programs. Without the “well typed” part, you are left with a proof that may or may not be correct and that may or may not make sense.
