Source sentences:
text: If two or more planar graphs all share the same vertex set, then it is possible to embed all these graphs in the plane, with the edges drawn as curves, so that each vertex has the same position in all the different drawings.
text: Directed edges are usually drawn as arrows and undirected edges as curves or line segments; see GraphTheory for examples.
