Fig. 3 — Two dimensional chemical space plot using ECFPs and UMAP dimension reduction for the set of molecules in three ranges (0–2.4 eV (left panel), 2.4–4.0 eV (middle panel) and 4.0–20 eV (right panel)) of the HOMO-LUMO gap. (a) the molecule distribution in structural space with all molecules in GDB-9 and (b) with 1% of molecules in ORNL-AISD. The color indicates the number of molecules populated in each region of the space.
