Figures show examples of so-called "Art Galleries" composed by visualization of the chemical space of different food chemical categories. The visual representations of chemical space were generated with t-SNE (Figures and), PCA (Figure ), and TMAPs (Figure ). Below each image (i.e., "digital paintings") is presented basic information of the "technique" (visualization method, allusive to the techniques used in paintings), descriptors, and chemicals (that would be meaningful information for a chemistry-oriented person to understand the data presented). Each visual representation of the chemical space or Artwork includes a "Title" that is reminiscent of the name of the piece of art or digital painting.
