Node
Also known as: Vertex
A node is a single thing in a graph - in GraphCanon, usually one tool, category, or entity.
A node (or vertex) is one item in a graph. It has a type and attributes, and it connects to other nodes through edges.
On its own a node is just a record. What makes it part of a graph is the set of relationships attached to it.
In GraphCanon
Tools, categories, tags, and entities are all nodes. A tool page is really a view of one node plus the edges radiating out from it.
