Random graph corresponds to the Erdös-Rényi model, with 1000 nodes and an average degree equal to 10. In this model, an edge between two nodes has a probability of 0.01. Colors are assigned according to the coreness: vertices with coreness 1 are violet, and the maximum coreness vertices are red, following the rainbow color scale. The node degree scale is also displayed, showing the maximum degree of the network. Return <-
