1Bent orthogonal grid drawing of planar graphs with high degree nodes All nodes are placed in a coarse integer grid and drawn with equal size. All edges are displayed by orthogonal open polygons in a fine grid without crossings.


1Bent orthogonal grid drawing of triconnected planar graphs with high degree nodes All nodes are placed in a coarse integer grid and drawn with equal size. All edges are displayed by orthogonal open polygons in a fine grid without crossings. The graph must be simple and triconnected.


Draw a planar graph in the visibility representation model.
If ORTHO_VISIBILITY_GIOTTO is specified, actually no visibility representation results, but the node segments are shrunk such that edges can enter a node at its left or right hand side. In the special case of 3planar graphs, one obtains small nodes.
