This is a preview of a new Addin in the next Reflector.Graph release: Type Tree Map.

A TreeMap is special 2D visualzation of a tree. Since, Reflector provides a tree (Assembly -> Module -> Namespace -> Type -> Members), I wondered if it was possible to visualize with a TreeMap. In .Net, there are 2 controls available that can render treemaps:

• A control in XAML, at CodeProject,
• A control from Microsoft Research,

I decided to use the later for creating the addin.

Note (1): The nodes represent each part of the type tree from assembly to the class members. Each node is clickable and brings the tree focus to the clicked element.
Note (2): Look at the treemap, and image the nodes are you Namespace/TestFixture/TestCase hierachy. Failed test in red, successfull test in green. Just imagine, that would be the ultimate progress bar for MbUnit!
Note (3): Thanks to Jamie (NUnitAddin) for the idea sharing on this.
