The famous iris dataset (the first sheet of the spreadsheet linked above) was first published in 1936 by Ronald
Fisher. The dataset contains 50 samples from 3 iris species: setosa, virginia, and versicolor. Four features are
measured, all in cm: sepal length, sepal width, petal length, and petal width.
