Plot: Add slihouette plot

[idomic]

Check out if sklearn supports it?

I have not added the visualization for clustered data plot as shown here since it would get complicated when features > 2. If it's needed I can spend more time on it.

Here you're referring to the scatter plot, right? I don't think we need that anyway, we can just focus on the silhouette plot.

Do we need to add anything elaborate with regards to the silhouette score? As of now there is call to the sklearn silhouette_score as in

We don't need to implement the score since it's already on scikit-learn

   , but I'm not sure if this is what we want.

1. But for the silhouettes it is covered for 2+ clusters? I also think we should try to put the time while we're at it on the clustered data plots since it usually comes together.
2. I think the score is good enough for now in addition to the plots.

yes it will work for 2+ clusters if number of features <=2. When features>2 we would need to plot a multi-dimensional plot I think. I'll check what options are there
