This improves upon previously known methods for networks where the minimum cost of the flow is small. We also show an application of our flow algorithm to a well-known graph drawing problem. Namely, we show ho

In this model, input to the layout module includes suggested positions for nodes and constraints over the node positions in the graph to be layed out. We describe three implementations of layout modules which are bas

On rectangle visibility graphs,e wish displayed on the drawing; it is natural to write this information inside the rectangle corresponding to the vertex. We call a graph that can be drawn in this fashion a ., or .. Our goal is to find classes of graphs that are RVGs. We obtain several results:

We give several approaches, heuristics as well as provably good algorithms, to represent planar graphs within this model. To this, we present a polynomial time algorithm to compute a bend-minimum orthogonal drawing under the restriction that the number of bends at each edge is at most 1.

The Library positions the nodes of a cluster on a radiating circle, and employs heuristics to reduce the crossings not only between edges incident to nodes of the same cluster but also between edges that connect different clusters.
