We could use the tikz library automata, and then instead of \draw, we use \node and \path, which will yield much cleaner latex, and more importantly, more easily customisable.
I suggest we add an option to resize the nodes. I tried a few things on the exported latex but nothing worked. But it is much easier with the automata library.
