Graph beginns to shake

[AJKellmann]

After a while, a graph may start to shake while holding it, even though the user doesn't move it.
The reason for this is the point that is used to calculate the angle between user and graph, which internally will change its position while moving the graph and due to the layout algorithms.

Calculating the middle of the graph and, based on correcting for that point leads to resonance between the two.
