Change in the geometrical congruence under the optimisation of embeddings obtained with Mercator⁸. We show the GC defined in (5) as a function of the number of epochs for the same networks (initially embedded with Mercator⁸) as in Fig. 4, where the colour of the curves encode the annealing scheme, the value of the curve shows the median over 20 samples (where the starting and ending values are marked by ’x’ symbols) and the shaded region around the curves is spanning between the 40\(^{\textrm{th}}\) and 60\(^{\textrm{th}}\) percentiles. The results are shown for the network of political books in panel (a), for a PSO network with \(N=128\) nodes in panel (b), a PSO network with \(N=256\) in panel (c), the metabolic network in panel (d), a PSO network with \(N=512\) nodes in panel (e), the unicodelang network in panel (f), the network between fictional characters in panel (g) and a PSO network with \(N=1024\) nodes in panel (h).
