label_scheme

type: int, default: 0, minimum: 0

Whether to treat a node whose name has the form |edgelabel|* as a special node representing an edge label.

• The default, label_scheme=0, produces no effect.
• If label_scheme=1, sfdp uses a penalty-based method to make that kind of node close to the center of its neighbor.
• With label_scheme=2, sfdp uses a penalty-based method to make that kind of node close to the old center of its neighbor.
• Finally, label_scheme=3 invokes a two-step process of overlap removal and straightening.
