# 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.
