Layout Phases

The main idea of the algorithm is to partition the nodes into layers and order the nodes within the layers such that edge crossings are reduced. Variants of this idea were first described in [Wa77, Ca80, STT81]. The method described here is mainly based on the algorithm by Sugiyama e.a. [STT81, EaSu90].

Layer layout consists of four phases (Fig. 15):
