They force you to enter information in a fairly linear fashion, and linear just doesn’t cut it sometimes. Sometimes, you want your work to be all over the place. Neo Darwinism

Molecular graphics (MG) is the discipline and philosophy of studying molecules and their properties through graphical representation. IUPAC limits the definition to representations on a "graphical display device". Ever since Dalton’s atoms and Kekulé’s benzene, there has been a rich history of hand-drawn atoms and molecules, and these representations have had an important influence on modern.
