[esiphday] Feynman diagrams by size

a Feynman diagram is intended to be numerically evaluated, producing a complex number, a probability amplitude in quantum mechanics.  draw a collection of Feynman diagrams, each with size corresponding to its evaluated magnitude.

color code by angle (argument)?  draw the diagrams on a complex plane?

the need for renormalization might become evident if larger diagrams are more numerous.
