Figure 4

Scale-free topology of a relationship network derived from the biological literature. Chilibot was used to retrieve the relationships within 3 sets of randomly selected genes (300 genes per group). The resulting networks contain 224, 116, and 138 nodes and 3018, 962, and 1912 relationships, respectively. The distribution of the average connectivity of the 3 groups follows the power-law (P(k) ~k-n, n = 1.21).
