# Plotting the results:

plt$.$plot $($range $(2,11),$ silhouette$\_$coefficients$)$

plt$.$xticks $($range $(2,11))$

plt$.$xlabel $("$Number of Clusters"$)$

plt$.$ylabel $("$Silhouette Coefficient"$)$

plt$.$grid$($True$)$

plt$.$show $()$ From the PCA silhouette$\_$coefficients plotting, how many clusters are suggested?
