I wonder if this is a good idea. The Schnyder algorithm tends to make the graph, while technically embedded in a planar way, very hard to look at. I would think twice about using it by default (although everything is linear in the number of vertices, so it's not computationally a bad idea). I've often wondered about an adapted spring algorithm which preserved faces, to apply after Schnyder... > * Implement the default layout of standard graphs using a > default_layout method rather than at construction time.
