get_transition_graph outputs

[hareball90]

the original documentation (transition) uses dot = modelTrans.get_transition_graph() giving an output of the model within an x-y axis

modelTrans.get_transition_graph() outputs the x-y axis figure and a clearer diagram (without axis)

dot = modelTrans.get_transition_graph(show=False) only outputs the clear diagram

Should the default of get_transition_graph() be the third option?
