ChemPlot features clustering of molecules in the reduced chemical space. The total number of clusters is defined by the n cluster parameter. In the visuals, a legend is included which shows the assigned color, cluster number, and share of coverage over the whole dataset for each cluster. Alternatively, users can interactively select and recolor clusters of their choice to visually distinguish them. This option is particularly convenient for evaluating the extrapolation performance of ML models, of saving the images of their plots both in their original and newly edited states. Furthermore, the interactive plot is created in HTML format, so that the users can export and embed it, for instance, to their own websites. Figure shows an example interactive plot of the BBBP dataset. The following code shows the interactive plot generation of the chemical space that has dimensionally been reduced by using the PCA method.
