RFC: to_dot accepts an AttributeDict for graph attributes

[ggggggggg]

To enable things like like overlap=false when using GraphViz.jl.

I'm a bit confused about all the to_dot and now to_dot_graph methods.
What's the difference between to_dot(::AttributeDict) and to_dot_graph(::AttributeDict)? Is the former used at all?

[ggggggggg]

Graph wide attributes have different formatting (eg no brackets) than node
attributes, to_dot_graph implements this formatting.

Thanks for the clarification. Could you just add a comment in the source to this effect?

Updated with comments.

Thanks @ggggggggg. Could you squash the commits into one? (git rebase -i HEAD~3).
Will merge after that.

[ggggggggg]

Ok.
