Molecular Graphics is a tool of researchers in chem-biological science and technology. It consists of two parts. One is graphic data generation either by X-ray crystallography or by model building. Another part is display options such as skeleton, ball-stick, and space-fill models. Various techniques have been developed for 3-dimensional viewing. We can expect increasing role of molecular graphics in such research areas as structure elucidation, molecular modeling, intercalation simulation, synthesis designs. Such technique is already widely accepted among pharmaceutical research institutions.
