Connectivity in networks, being anything from computers on the internet to 
atoms in a molecule.

Most graphs are best represented as sum types (and abstract references, like 
identifiers) in FPLs like Haskell though, rather than using a more general 
representation. Abstract syntax trees in compilers and interpreters, and 
scene graphs in computer graphics being two obvious examples.
