Wgraph:Demo invisible

• invisible hides a graphical object
• invisible objects still influence graph layout
• if an edge is invisible the nodes it connects will still be drawn
• if an object is invisible, its edges will still be drawn
• if the edges connected to an object are set to invisible the node does not become single by that.
• label texts of invisible edges influence the layout. As a consequence, S3 is bigger than S2
