Dragging the boxes around is easy, you just need to remember the positions, as Alan pointed out. The difficult part is the routing of the arrows. When you move a box then any arrows connected to it also have to move - without auto layout you end up with arrows going through (or behind) boxes. If dot will just do the arrow routing then it may be possible - I'll check if that's possible.
