14 | KLay Planar encompasses planarization based layout algorithms. The main approach employed here is the //topology-shape-metrics// approach, which consists of the following phases: | ||
15 | |||
16 | 1. Planar subgraph - Remove edges until the resulting subgraph is planar. The goal is to minimize the number of removed edges. | ||
17 | 1. Edge insertion - Reinsert the previously removed edges and replace all resulting crossings by new dummy nodes. The result is a planar embedding (//topology//). The goal is to minimize the number of introduced dummy nodes. | ||
18 | 1. Orthogonalization - Find an orthogonal form by computing a series left or right bends for each edge (//shape//). The goal is to minimize the number of bends. | ||
19 | 1. Compaction - Determine specific coordinates for nodes and edge bend points (//metrics//). The goal is to minimize the length of edge segments. | ||

21 | The implementation is currently in progress... |
