In charting the “drug-likeness” of related compounds (represented as dots), a few tight clusters (left) indicate chemical similarity. Smaller, dispersed bunches and free-floating dots (right, for a different type of compound) indicate a lot of chemical variation. The redder the dots, the closer the compounds are to a QED value of 1, meaning they are the most druglike. Full Story G.R. Bickerton et al/Nature Chemistry 2012
