The "-omics" fields and neuroscience have started exploiting graph structures to describe metabolic interactions, gene regulatory networks, and organic neural networks, among other things. fMRI imaging, for example, can be described as representing a temporal network of oxygen levels in the brain. The idea of creating novel purpose-built graphs and embedding ourselves in them, in addition to modeling existing networks using graph structures, is interesting. I think social media and other networking technologies are the most current examples, and the first decade of the internet was probably the best example of an intentionally-constructed dynamic knowledge graph.
