But a graph has nodes and edges. Nodes, in this case, can be particles.. I guess? But what are the edges? When a "simple rule" is applied to a collection of particles, what is the force that connects them after the interaction? I read some of the material in detail and skimmed some of the rest, but there was a lot of setup and cool graph visualizations and not a lot speaking to this core question.
Disclaimer: I'm not a theoretical physicist but I have read "Quantum Physics for Babies" at least 50 times.
