from sklearn import datasets
import pandas as pd

whole_data = datasets.load_iris()
whole_data

print('The full description of the dataset:\n',whole_data['DESCR'])

x_axis = whole_data.data[:,2]  # Petal Length
y_axis = whole_data.data[:, 3]  # Petal Width

# Plotting
import matplotlib.pyplot as plt

plt.scatter(x_axis, y_axis, c=whole_data.target)   
plt.title("Violet: Setosa, Green: Versicolor, Yellow: Virginica")
plt.show()

I have chosen petal width and petal length for visualization as they show high class correlation ... why just me?
