[vtkusers] Displaying graphs side by side

[Eric E. Monson]

Well, it seems to basically work in Python (just directly translating your code) -- at least it doesn't crash. The only strange thing is that selections don't work on the first (left) graph. All of the other interactions work, and the rubber band is drawn correctly, but nothing gets selected unless you're working on the right graph...

Just a note: I don't think you don't need to set the Points on the graphs since vtkGraphLayoutView includes the "layout", which sets the points. If you want to "disable" the layout and just set the points manually, you should probably use SetLayoutStrategyToPassThrough() on the view.
