Building a Markov Chain Graph (directed graph) with large number of nodes/states

I have a transition probability matrix with 205 states or nodes and I want to visualize it as a directed graph. I used Matlab's digraph and graphplot functions but the edges overlap on top of each other and it is very difficult to analyze it.

Is there any other function or toolbox in MATLAB to visualize such type of directed graphs with large number of nodes?

Thank you

What layout are you using to have MATLAB determine the coordinates at which the nodes should be plotted? Depending on how sparsely populated your transition matrix is the 'layered' layout may be useful.
