To the best of my understanding, this function performs the PCA and then chooses the top two pc and plot those on 2D. WebbFrom the scatter plot, we can see that there are 3 distinct clusters in the data. This confirms that the value of K that aligns with the number of clusters in the data is 3. We can also see that increasing the value of K beyond 3 does not necessarily improve the clustering performance.
