This is an animation of a "growing entourage" plot during plotting. Such plots take images located in a high-dimensional similarity space, cluster them by some method, and project the clusters to a 2D canvas. Here, the images are grouped by agglomerative hierarchical clustering in a 95-dimensional stylistic similarity space. The centroids of each cluster are then projected to 2D by PCA, and the centroids then take turns adding members to their "entourages", in order of visual similarity to the centroid. New members occupy the open square nearest their centroids. Territorial conflicts are settled by this principle.
