Use ID as vertex label when generating DOT output #45

Closed rlipscombe closed 2 years ago

rlipscombe commented 2 years ago

If you have vertices with the same label, the DOT output treats them as the same vertex.

Use the raw ID to ensure that vertices aren't merged.

Probably doesn't play nice with the change in https://github.com/bitwalker/libgraph/issues/44

I haven't tested with an example file yet, but does this preserve readability of the output (i.e. do you still see the vertex label for each vertex?). If you serialize a graph and all you see are random ids, I imagine that's not super useful. Assuming that isn't the case, looks good to me otherwise!

It uses [label=#{v_label}] to preserve the labels. I can't guarantee that I've not broken something else, though.
