English: Biplot of the Spectral Map Analysis of the Iris flower data set collected by Edgar Anderson (1897-1969). The biplot visualizes 100% of the original data set variance as contrast. The biplot barycenter is indicated with the red-green cross hair. The measurements are visualized as squares. The objects are visualized with three symbols by Iris flower type: dots for setosa, squares for versicolor and upward triangles for virginica. The JPG was created with Spectramap.
