Hi all,
I'm using *SageMath version 10.1.beta1*, and I have dot2tex and graphviz
installed. I checked that following line produces a nice PDF of the tableau.
sage: T = Tableau([[1,2,2], [2,3]]); view(T)
However, I found that I can not plot or view any digraphs. Thanks!
sage: G = graphs.PetersenGraph().to_directed()
sage: G.plot()
