2-mode-2-way seriation. a, c, e: random data order b, d, f: seriated ones. The data are shown on scaled heatmaps. a, b yearly air pollution data at 26 stations in 2017 (POL_YEAR dataset), the seriated order of the variables (columns): PM2.5, PM10, O3, NO2, NOX, NO, SO2, CO, BENZOL c–d) components of celadon ceramics (CERAMIC dataset) e–f reaction and species in a gasoline combustion model (REAC dataset), blue denotes the three reactants, red ones are H2O and CO2
