Quick reply…The layout of this graph is based solely on the physics of attraction and repulsion between connections. This is a map, but it’s one that cannot be translated to Cartesian-style definitive [x,y] (or even z) coordinates. The layout is important, but only in terms of the relative placement and grouping of the actors/nodes. This is precisely the advantage of using physics to map out these types of hyperlink-based ecosystems. ‘Surrounded’ is a perfectly reasonable way to frame part of what’s going on here, as the outer nodes are far outside of the center of the network and are heavily linking into its central actors. If you’re interested, I recommend looking up ‘force-directed’ algorithms for network (& especially social network) layout. It’s how advertisers know who is most influential in your Facebook network, how Google gives you relevant search results, and how you get specific LinkedIn/Twitter, etc. ‘friend recommendations’ outside your existing network. It’s a fascinating topic. Hope this helps clarify.
