Hi,
I am looking at implementing a automatic mindmap diagram layout in order to enforce the position of the items dropped as well as update the layout whenever a branch is expanded or collapsed. The basic behavior I am looking for is similar to the one provided as a sample with the mindmap layout sample. One of the tricky part is to update the existing item's position when the user expands a node in order to avoid items overlap. Do you recommand a particular approach in this area. XMind does a pretty good job in this area and this is the kind of behavior I am trying to implement.
