Can we draw mixed graphs( graphs with some edges oriented while some are not) in sagemath?

I am not sure about your motivation, but a possibility is to use oriented graphs, and put edges from both `a`

to `b`

and `b`

to `a`

when you want to consider `(a,b)`

as a non-oriented edge. This double-edge construction is classical to define non-oriented graphs.

Yes I know that. But I need the diagrams as mixed graph. I need for several purposes. For example I need to print a mixed graph(with some edges without orientation), want its latex commands. Of course I need some operations on mixed graphs, that I had already done using the method you have mentioned.
