The test cases are here - you could review LineGraphGeneratorTest if you have
questions about that class:
-
http://svn.osgeo.org/geotools/trunk/modules/extension/graph/src/test/java/org/geotools/graph/
You can also review the uDig graph module (which provides an interactive
example you could use). Try them out with a debugger; other than that there are
the docs on the website.
I would love to make a tutorial for this stuff but have not found the time /
funding. I see you are a consultant so I am sure you can understand - there are
additional support options listed here
http://docs.geotools.org/latest/userguide/welcome/support.html if you need more
direct support in order to meet a deadline.

All of the data generated in your IT infrastructure is seriously valuable.
Why? It contains a definitive record of application performance, security
threats, fraudulent activity, and more. Splunk takes this data and makes
sense of it. IT sense. And common sense.
