After generating the TikZ code with Graphic, I just added the \placefigures by hand to display the output, and wasn't as careful as I should have been (and would have been for a "real" document). > Plus, I am surprised that > \path (v0) edge[e] node[l] {$$} (v2); > actually compiles! I will admit I was surprised a long time ago when I first saw that $$ compiles; I've been using that for so long I don't know where I originally saw that it worked. (Maybe TikZ does something heavy-handed to make sure you don't try to do display math inside a node.) I could output the code without it, but I wanted to make the TikZ as easy to (post-)edit by hand as possible. (Which comes at the cost of having spurious math-on/math-off characters.) Cheers.
