Along the lines of what Marc said: Use two graph-implementations that share the same interface regarding the algorithms, but one will emit events to some observer for each operation on the graph - edge/node adding/removal, attribute changing and so forth. Thus the algorithm is kept clean, and all that you can visualize anyway is available to you. diez -- http://mail.python.org/mailman/listinfo/python-list
