Is there any way to visualize learned Bayes network in a form of a Bayes Graph from one of the nodes like Naive Bayes Learner or any weka bayes related nodes?

The BayesNet node in the Weka extension bring along a Graph view, is this what you are looking for?

I was looking for something more related to visualizing output from i.e. Random Tree Forest weka node like in decision treen to image node from data mining set. In general something like classifier visualization.
