SimpleGraph.ConnectedComponent.toSimpleGraph

{V : Type u} → {G : SimpleGraph V} → (C : G.ConnectedComponent) → SimpleGraph ↥C

Given a connected component C of a simple graph G, produce the induced graph on C. The declaration connected_toSimpleGraph shows it is connected, and toSimpleGraph_hom provides the homomorphism back to G.
