I am using the diagram control to draw a Yes/No decision tree, where every intermediary node has at most two paths. I want a child node for the "yes" path to always be drawn to the left of it's sibling, the "no" path.

How can I do this?

I tried adding the yes nodes to the Nodes collection using Insert and an index of 0 to place them at the front of the collection, before any of the No nodes, but the diagram doesn't seem to draw in the order of the collection.
