MGraph Object Model Display Library

Here is the documentation (a very succinct one, but contains all you need).

The MGraph Object Model is a general graph representation and manipulation mechanism where the representation part is usually textual.

This library takes the textual representation of a graph and visualizes it on a WPF Canvas.

cf. The MGraph Object Model article on MSDN.

Some examples (see the last item for the "Villagers" example of the aforementioned article):

• Composite Node
• Collection
• Record
• Tuple
• List
• Another List
• Simple "Villagers"
• "Villagers"

For a self-referential annotation of the shapes and colors used, go to NodeKinds Legend

Composite node example:

Canvas canvas = new ObjectModel().Display("Person {Name=>'Ciper', 47, 'sixpairs\n.com'}");

                              Tail => { Head => 2,
                              Tail => {} } } }
                  ");
