Currently we have no way of testing this other than executing the generated graph; instead we stop at the rel level. 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).

Using the DOT format might be nice so we can just pipe it into graphviz for visualization:

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.
