Export Your Code Graph with vg export

Your code graph is most useful when you can feed it into other tools — a Neo4j database, a Graphviz render, or a Markdown doc. vg export outputs the code map in a range of formats.

Prerequisites

• A built code graph from vg build

Steps

1. Build the graph

vg build

2. Export the graph

vg export

vg export writes the code map. Supported formats include JSON, GraphML, Graphviz DOT, Neo4j Cypher, Markdown, HTML, CycloneDX SBOM, and SPDX.

3. Pick a format

Choose the format with --format:

vg export --format graphml

Use DOT for Graphviz rendering, Cypher to load into Neo4j, or JSON for custom tooling.

4. Write to a file

Send the output to a file with --out:

vg export --format graphml --out graph.graphml

5. Load it downstream

Load the exported artifact into your target tool — render a DOT file with Graphviz, import Cypher into Neo4j, or publish the Markdown export as documentation.

Verification

Confirm the exported file exists and is non-empty in the format you chose. Opening it in the target tool (Graphviz, Neo4j, a Markdown viewer) should render your graph.
