Question $3\mathrm{.}1$: Given what you know about how a Cluster Plot works $($see above link$),$ describe how the three features $($gender$,$ emotion, and identity$)$ relate to the clustering of images by similarity. Specifically, think about where there are the greatest number of overlapping pixels across the different images from each of the different categories $($all the happy vs$.$ sad, female vs$.$ male, and within each individual$).$
