That's unfortunate and I think an oversight. When doing force-directed layout the node positions should be drawn back to the centre of the view port (or in the more general case, the centre of mass of the original set of node positions). From looking at the code for force layout, this doesn't happen. If that were fixed, then the requirement for making a constraint would go away because it would not be possible for a graph to wander off the view port and it would not be possible for a user to drag the graph out either.
