refactor: use "diagram" instead of "graph"

Change everywhere to use the word "diagram" instead of "graph. Diagram
seems like the better word. It's mostly used in comments and
documentation, but there was one filename and one trait name that
needed changing.

I used "rg -iw graph" and "find -iname '*graph*'" to find everywhere
that needed changing.
