The presented method provides a generic approach to network visualization. It produces the drawings above which previously had to be produced using two totally different algorithms: (a) is a drawing of a gene regulatory network (showing the indirect interaction of genes through their RNA and protein expression products) using a Sugiyama layered layout style (note the two bi-fan motifs highlighted and drawn similarly), (b) is a protein interaction network (showing the interaction of proteins in a cell) using a force-directed layout style (Figure 7 shows the affect of adding constraints to this layout).
