Abstract

We report on some extensions of the Kandinsky model: A new and highly nontrivial technique to incorporate nonplanar drawings into the Kandinsky model in the same way as in the GIOTTO approach is presented. This means a major step towards the practical usability of our approach. The used technique even gives new insights for the solvability of network flow problems. Another variant of Kandinsky ensures a minimal size of the vertices removing the requirement of uniform size of each vertex. We present a new technique to evaluate our approach with respect to the area and the number of bends, and to perform a reasonable comparison with the GIOTTO approach.
