How do I create a tree diagram in pages '08?

Aparently the answer is that it cannot be done in Pages '08. I did however find a solution that did not require me to spend over $100. www.dabbleboard.com I'm sure it was a little more labor intensive than the charting solutions mentioned above but once the image was created, I saved it on my computer and their server for later reuse. Since I don't anticipate a recurring need to create similar charts, I will spend 5 extra minutes instead of spending $100.
