I have designed a page to graph the whole transition automa based on the same graphviz_api we use to graph the relationship.
The script creates a graph for each access level (from viewer to manager) in order to give evidence of what transition an user can perform or not based on his access level. The grey arrows mean transition not allowed for that access level but foreseen (i.e. allowed for a greater access level). The black arrows means transition allowed. The blu arrows are just to highlight the "reopen" transitions.

It's just a draft and I would like to have some feedback from you in order to improve it. Just copy the files and call the adm_status_automa.php
