# Log-log plot comparison between a random and real world networks

I know that random networks have a bell curve (Poisson distribution) in their degree distribution and scale free networks have a straight line in their log-log plots. However, how do the log-log plots of random networks look like. How do I differentiate between the log-log plots of real world and random networks

curve((function(x) dpois(10, x))(x), 0.1, 100, log="xy")
