Summary
To lowest-order weak interactions in the standard model, we point out that a complete graph description of two-body mesonic B-(or D-) decays needs ten topologically different quark diagrams. The two-body baryonic B-decays can be illustrated in terms of five diagrams. We remarks a variety of features of the graph language. Some pure channels of mesonic B-decays, which can be used to test the quark-diagram scheme, are discussed in some detail.
