Lets say I have developed a Binary Tree structure in a module creating my own user defined Type named "BTree"...

My problem is... How can I graph this tree I created?
I need to be able to graph or paint at least 4 levels. I would appreciate help.

Thank you in advance

This would be somewhat what I would need...
