Applications of chemical space concept have progressed from drug discovery to other areas in chemistry, including organic synthesis, food chemistry, and material sciences, to name a few examples reviewed in the literature . A key distinction between the different types of the systematic representations of chemical spaces in compound datasets lies in the type of properties or descriptors that are used to represent the compounds of interest. For instance, the nature of the descriptors used to represent small organic molecules is typically different from that describing chemicals with applications in material sciences. In some instances, the qualitative concept of chemical space is actively used to guide drug discovery projects; however, developing a consistent method to visually represent chemical space remains elusive because of the challenge in generating a consistent manner of representing chemical structures. A typical method employed in this area includes analyzing the chemical space of metalcontaining compounds .
