In recent years, with a significant an increasing number of molecules to be analyzed, novel methods to generate visual representations of chemical space have been developed. While interpreting such visualizations, one should consider that they are approximations and that the "true" chemical space is defined by the complete set of descriptors used. Because it is challenging to select the appropriate method according to the expected qualities of the visualization, it is advisable to complement the visual (e.g., qualitative) analysis of chemical space with a quantitative analysis considering the entire multidimensional space. In this regard, it is advisable to consider consensus approaches: multiple representations of chemical space (at least more than one), because each visualization will capture part of the "true" chemical space.
