Abstract
The cluster adjacency graph of a flat clustered graph C(G,T) is the graph A whose vertices are the clusters in T and whose edges connect clusters containing vertices that are adjacent in G. A multilevel drawing of a clustered graph C consists of a straight-line c-planar drawing of C in which the clusters are drawn as convex regions and of a straight-line planar drawing of A such that each vertex a ∈ A is drawn in the cluster corresponding to a and such that no edge (a 1,a 2) ∈ A intersects any cluster different from a 1 and a 2. In this paper, we show that every c-planar flat clustered graph admits a multilevel drawing.
