(a–d) Are respectively the spatial distributions of Hub-1 ~ Hub-4 from Eq. (1), where α = 2.0, L = 10 and each distribution are from 105 example networks. According to distribution peaks, each distribution is divided into several distribution areas. For the same hub, different distribution areas are indexed by different colors and Roman numerals.
