Exercise

Create a dendrogram

Dendrograms are branching diagrams that show the merging of clusters as we move through the distance matrix. Let us use the Comic Con footfall data to create a dendrogram.

The data is stored in a Pandas data frame, comic_con. x_scaled and y_scaled are the column names of the standardized X and Y coordinates of people at a given point in time. cluster_labels has the cluster labels. A linkage object is stored in the variable distance_matrix.
