Besides usefulness in a test framework, a decent rendering of stream graphs would also be helpful in tracing/debugging (reading XMI may lead to blindness or insanity).

So far none of the attempts at XML formats for graph representation (e.g. XGMML) seem to have caught on.

Another visualization option is to use JGraph/JGraphT like I did for the plannerviz plugin. But graphviz probably does a better job.
