Plot sum of squared errors

Now you will plot the sum of squared errors for each value of k and identify if there is an elbow. This will guide you towards the recommended number of clusters to use.

The sum of squared errors is loaded as a dictionary called sse from the previous exercise. matplotlib.pyplot was loaded as plt, and seaborn as sns.

You can explore the dictionary in the console.
