What exactly is a "valence bond diagram"?
How can these be drawn for complex organic molecules?

Meh, figured it out. For anyone wondering, since google results are scarce and buried in academic papers, they are the sort of daisy-like diagrams of overlapping orbitals, denoting the electron spin-pairing in sigma/pi bonds.

I'm guessing this refers to Valence Bond Theory, but I have no idea what a "valence bond diagram" is, never heard of it.

There is something known as a molecular orbital diagram, though, as a part of molecular orbital theory. I wouldn't say that's the formal or official name of the diagrams, though, it's just a map of the relative energies of molecular orbitals and in what configuration electrons occupy them. It explains many properties of materials observed in nature regarding the behavior of electrons in both molecules and bulk materials.
