source graph

The graph where the markdown originally comes from.

The source graph is represented by a combination of the source directory (like a vault in Obsidian, for example) and then an unconstrained expansion of a graph from the initial site page. The unconstrained "source graph" is pretty impractical, though, so we don't deal with it much... it's like with the idea of 6 degrees of separation. With no constraints almost everything connects to everything else. It's impractical to deal with.

So In practice the source graph is never directly considered as a whole. Rather, what the publisher interacts with is the raw working graph, which starts from the same point but does constrained graph expansion instead, which often limits its scope significantly.
