# Graph document schema

A graph is a JSON document (`*.graph.json`) that the editor opens as nodes and
`noodlelab run` and `noodlelab verify` run headless. This is its JSON schema,
generated from `noodlelab.core.graph.GraphDocument`. The examples that come with
noodlelab are the best reference for real graphs, and [Graphs and
reports](../agents/graphs-and-reports.md) explains how to build one.
