Hubs contain axons that point to other hubs, with each axon connecting a hub to only one other hub. A hub can be pointed to by multiple axons from different hubs. Pseudocode defines a Hub class with attributes like name and IQ, and a chain of axon connections, and an Axon class specifying the connection type and links to the outgoing hub and next axon. Basic network structures using hubs and axons can model many real-world domains.
