 To expand nodes recursively the user can choose a context menu option '''Expand nodes recursively'''. To make recursive expansion, the user must enter a recursion depth. Recursion depth is a positive integer number usually bigger that 1.

 == Hyperbolic projection and projection curvature ==
-The graph topic panel views the graph in a hyperbolic perpective. Hyperbolic perspective views nodes in the center bigger. The user can change the strength of the hyperbolic perpective. The strength, or curvature, is changed by rolling the mouse wheel while the SHIFT key is pressed down. If the hyperbolic strength, curvature, is large enough, Wandora views a graph horizon, a gray circle around the graph. No node and no edge can ever cross the graph horizon. Also, the curve widget button can be used to change the hyperbolic strength.

 The graph is [http://en.wikipedia.org/wiki/Force-directed_graph_drawing force-directed] i.e. nodes are assigned forces based on their positions, and these forces have an effect to the motion of the nodes.
-Thus, the graph is animated and node positions change automaically. As the time passes, the graph gets usually clearer and finds a balance. However, some times when nodes have very much connections i.e. edges between nodes, the graph may end up animating very rapidly and the animation loops. In this case it is good to stop the animation and filter out some edges.
