# Edge (relationship)

_Also known as: Relationship, Relation_

**An edge is a connection between two nodes - the relationship that makes a graph a graph.**

An **edge** links two nodes. It can be directed (A points to B) and can carry a type and an explanation, so the connection means something specific rather than just "related".

Edges are what you traverse: follow them to move from a tool to its alternatives, its integrations, or the tool that superseded it.

## In GraphCanon

GraphCanon separates **curated graph edges** (typed relationships from ingest/enrich) from **category neighbours** (same-category discovery). Curated edges are decision-grade; neighbours are exploratory.
