The dataset contains four measurements on flowers from 150 different plants. The first
50 flowers were irises of the species setosa. The next 50 were irises of the species
versicolor. The last 50 were of the species virginica.
A scatterplot of two of the numeric measurements, PetalLength and PetalWidth,
suggests that those two measurements alone will be useful in classifying the flowers
according to species.
