Visualize Maven modules

To quickly get a overview of a big Maven project it is often useful to get a visual view of the modules and their dependencies. The Maven Dependency graph plugin generates such a dependency graph as a png-file.

<!--
sudo aptitude install graphviz
Artifact javax.inject:javax.inject:1 is named javax.inject:inject:1.0 in maven-depgraph-plugin.
This artifact must thus be manually added to your repository manager.

mvn depgraph:depgraph -P depgraph
