a Heatmap of Pearson correlation between local dimension and node infectiousness for small-world graph (n = 100, average degree k = 10, probability of rewiring p = 0.015). The black line is the average proportion of infected nodes given a single-seed node for a given infection probability β. The transition from low to high proportion of infected nodes indicates the critical point while the dashed line is the maximum correlation for each β. b We vary the probability of rewiring edges p of small world graphs and display i the diffusion time that maximises the correlation between local dimension and infectiousness for varying β, and ii the associated correlation coefficient. The correlation is near one close to criticality and above 0.8 for a large range of β. We repeat the analysis in a for c a Delaunay grid graph (n = 400) and d the European powergrid network to observe a similar linear relationships between scale and infection probability β prior to criticality.
