Networks topologies considered in the paper. Scale-free networks with gullible communities with different values of ρ: highly segregated, with ρ=0.05 (a) and well mixed, or not segregated, with ρ=0.8 (b). We also show some visualizations of networks generated by means of Schelling configurations with different values of density D and preference P: D=0.7, P=0.5 in (c) and P: D=0.9, P=0.3 in (d). Different visualizations of Shelling based networks are shown to emphasize the segregation patterns within the grid, than to allow an intuitive comparison with scale-free networks with the application of a force-based layout
