We should really do that - a lot of infrastructure to do this already is available in the C rewrite by Simon, and it's just a matter of doing a clean import of the `systemctl dot` logic from there on, but I have to check that we have all the data available through the DBus interface, it might ultimately be slower than `systemctl dot`, but I don't think that should stop us. I'm pushing for cleaning up Simon's patch and including it in the tree - it will directly replace the python code since the output and interface is consistent with the old output.
