Abstract: We give an explicit calculation of the Wu invariants for immersions of afinite graph into the plane and classify all generic immersions of a graph intothe plane up to regular homotopy by the Wu invariant. This result is ageneralization of the fact that two plane curves are regularly homotopic if andonly if they have the same rotation number.
