The author introduces new invariants of arbitrary graphs in \(S^3\) which correspond to Yamada polynomials for graphs with constant valence 3. The invariants are computable and powerful enough to detect some delicate differences of embeddings peculiar to graphs. Two descriptions of the invariants are given and a few examples are computed.
