It all plugable, see GrapherServlet::doRenderGraph:
* graph creator; modules, services, old MC, ...
* dependency type; i-depend-on, dependes-on-me, unresolved, ...
* dependency filter; filter components
* layout; actual vertices placement (missing jgraph-layout lib here)
* renderer; jpg, gif, png, svg, html, ...

You're welcome to write such renderer.

> btw. noob question - what is the name one should use if I deploy foo.war to the server as parameter to this grapher ? 

?extension=single-module&initial-value=<MODULE_NAME>

Where module_name in this would be: deployment.foo.war:main

I need to check if this actually works; 
I mean, do I have access to this module outside Grapher app.

The awesome visualization tool that you did for MC dependencies made me think of you for this idea.  I'm not sure if it is even possible or wanted.  But, how do our users figure out, what is going on in classloader land, with regard to what classes/jars are accessible to each module or deployment (maybe both?).
