In this model, a nook’s higher when it’s a more central node in the graph of nooks. Usually a central node looks bigger ‘cause it has more edges (thus the edges fill space better and need more space to be seen clearly), but Duncan chose to instead represent this with bubbles of varying size ’cause the felt sense is closer to that.
Probably he also should’ve drawn them the standard way, and made explicit that we’re talking about centrality; I didn’t understand well until I wrote this comment.

Actually, varying size seems a very good way to represent centrality, since it shows that a node surrounded by central nodes will also be central.
