Figure 1

An example computation of the regionalization index (\(\chi (G)\)) across a set simple, stylized graphs. On the left, we show the normalized list plot of singular values of a star (blue-star), tree (orange-cross), line (green-triangle) and cycle (red-circle) graph with seven nodes each. On the right, we show the entropy list plot for each graph, i.e., the normalized singular values, and \(\chi(G)\) is exactly the area under this curve (corresponding to values as listed in the caption)
