Histograms of module sizes (Int-PI and Lit-PI) and Power Laws. Distributional aspects of module sizes for Int-PI and Lit-PI datasets, and corresponding power laws (from Matlab scripts plfit.m, plplot.m in http://www.santafe.edu/~aaronc/powerlaws webcite). Values for alpha approximately between 2 and 3 are typically expected.
