JHotDraw 7 Net Sample Application

Each NodeFigure has four connection points which can be used to link it to other nodes.

NodeFigures are connected using 'plain' ConnectionFigures. Since Net does not add semantics to the connections between nodes, it does not need to provide its own subclass of ConnectionFigure.
