Comment from OP:
I am executing the operation illustrated AVL tree, I use C # to implement but do not have to carry the idea, the idea is you can help me. For example, after performing the operations add, delete, balanced finish, I proceeded to draw trees, how can I do?

I assume you are able to use the GDI+ API for drawing lines and circles.

I can suggest a way to obtain a graphical representation of such trees that makes sense:

- for the abscissas of the nodes, use either the node rank (from 0 to NumberOfNodes-1), or the node key (assuming numerical values, from Key[0] to key[NumberOfNodes-1]);

- for the ordinates, use the depth information (0 at the root, increasing by 1 unit at each level).

Obviously, you will have to scale those values so that they nicely fit in the drawing window. Linear transforms of the coordinates will do. (Lookup Windows/Viewport tutorials on the Web.)
