what does it show?

It shows a treemap of the hierarchical graph of the moose model of the FAMIX codebase ;)

First I created a moose model, which went something like this:

[...]
importer model: model;
addFromPackagesNamed: (MooseScripts packageNamesFor: 'Famix*');
[...]

Then I created a hiGraph of the moose model. The hiGraph can then display itself as a treemap.

The big rectangle on the lower right side is a method called mse with a weight of 5067 LOC and is, surprise, inside the package of VerveineJTestRessource.

In smalltalk we have a pretty flat hierarchy. So the outermost rectangle is a FAMIXNamespace, the inner containment rectangles (with the gray borders) are all FAMIXClasses, and the inner rectangles are all FAMIXMethods.

If you compare the FAMIX treemap to the one of argoUML, you can see that we got a much more nested hierarchy (nested java packages). The darker the gray borders of the containment rectangles, the deeper the nesting level.
