-Random graph generator may not have real life implementations but it offers nice test suite for Wandora and topics maps. It is also interesting to note that the association distribution of random topic maps are variations of bell curves rather than power law curves found in many real life graphs. You should also note that creating very dense topic map requires much memory as the number of associations increases. Below is an example of layer connection statistics after random graphs generator with 5000 topics and 0.05 association probability.
