If every individual was only acquainted with others who lived near them, you would expect it to require many more than six hops to send a message from Kansas to Massachusetts, because each hop could only cross a short distance. Such a network can be modeled as a k-ring: nodes arranged around a circle, with each node connected to the nearest k/2 nodes on each side. The following example creates and visualizes a four-ring using the watts_strogatz_graph() function (which will be discussed later in the section).
G_small_ring = nx.watts_strogatz_graph(16, 4, 0)pos = nx.circular_layout(G_small_ring)nx.draw_networkx(G_small_ring, pos=pos, with_labels=False) ...
