My intention in writing this article was to provide a dramatic and easy to see example of the importance of the row and column orders in a heatmap and the benefits of seriation. To do so, I chose a dataset which is actually particularly amenable to seriation via the TSP approach: adjacent rows and columns in an image are extremely similar to each other, far more so than in most other kinds of datasets. Clearly, applying seriation techniques to most datasets will not generally yield photographs of me
