you manipulate a data structure that contains vertices and edges. there is more about it here http://inconvergent.net/snek-is-not-an-acronym/.

snk is an instance of snek, so it contains a realisation of the structure and its current state.

so...snk is a graph?

Most data structures are graphs. This one just happens to be "self-aware" enough to use graph terminology.

[inconvergent]

yes, it is.
