Constellation plots are useful to depict the chemical space of chemical libraries containing several analog series. They are helpful at concisely depicting the structure-activity (property) relationships -SA(P)Rin a summarized representation of the data set, as analog series can be represented in fewer data points than individual compounds. Of note, only a fraction of the total data is presented in the constellation plot: the compounds forming analog series; in this case, we included only analog series consisting of at least three compounds. Recently, constellation plots have been used to describe a library of antidiabetic natural products and a collection of tubulin inhibitors.
