None of the built-in embeddings display my graphs the way I want them. How can I create my own embedding option? I want to display my graphs as regular polygons with vertex labels in fixed positions. Circular embedding will display graphs as edges of polygons, but moves the labels around in order to keep edges on the peripheries of the polygons. I don't want that. I want to display an array of graphs that display the different ways the edges are placed. When vertices are permuted, you have to read their labels to understand what's going on.
