First of all, we create a sample data for clustering.
We'll use `make_blobs` from sklearn to do so.

Initialising the cluster centroids is a key challenge in KMeans.
KMeans++ starts by selecting random centroid.
Then uses a probability-based approach to select next centroid that is far away from the previously chosen centroids.
This makes the initialization spread out.

Let's apply K-Means++ to the data we just created! π
