This class manages a graph consisting of DisplayGraphNode 's The graph can be displayed and layouted in a QGraphicsScene. For layouting a spring embedder algorithm is used, additional a control widget can be rendered into the QGraphicsView which can be used to control parameters of the spring embedder
