Create Normalized data frame

Use Elbow Graph to find optimum number of clusters (K value) from K values range

The K-means algorithm aims to choose centroids that minimise the inertia, or within-cluster sum-of-squares criterion WCSS

Plot K values range vs WCSS to get Elbow graph for choosing K (no. of clusters)

Build Cluster algorithm using K=4 and K=3

Assign clusters to the data set

Compute the centroids

Plot the clusters
