AI Diagram Generator for dbt

Visualize models, tests, and exposures without digging through DAG screenshots.

7 min readAnalytics engineers and data developersFocus: dbt lineage and contracts

Top use cases

Save the prompts you reuse and regenerate diagrams every time your stack changes.

Summarize model lineage for PR reviews and onboarding

Map tests and contracts to the models they protect

Show exposures and downstream BI dependencies

Highlight performance hotspots and refactoring targets

Workflow that ships

1

Export model metadata (refs, tests, exposures). Feed key pieces into the prompt.

2

Ask AI to draw lineage grouped by folder or domain with tests annotated.

3

Add owners, SLAs, and contract status per model.

4

Publish diagrams to PR templates and onboarding docs.

Prompt recipes

Copy, tweak, and save in your repo so regenerations stay consistent.

"Create a dbt lineage view grouped by marts with tests per model and exposures for Looker and Hex."

"Show contracts, owners, and freshness for core models: customers, orders, subscriptions."

"Highlight long-running models and their dependencies for performance tuning."

Quality checklist

Models display owner, SLA, and test coverage.

Refs and exposures are labeled so reviewers see blast radius.

Contracts and freshness expectations are visible.

Performance notes (runtime, cost) marked on heavy models.

Why use Datadef

Prompt-to-canvas in seconds

Generate React Flow diagrams from prompts, then tweak nodes, metadata, and z-index with live collaboration.

Always in sync

Save prompts alongside canvas versions so you can regenerate diagrams as schemas, services, or policies change.

Shareable and auditable

Export PNG/SVG for decks, or share live canvases with lineage, SLAs, and runbook links for reviewers.

Built for data teams

Support data mesh, lakehouse, and streaming patterns with typed nodes for tables, pipelines, services, and governance layers.

FAQ

How do I avoid clutter with big projects?

Group by domain or folder and collapse non-critical paths. Keep critical models expanded with tests and exposures.

Can I show contracts?

Yes. Add contract status to node labels and let AI surface models lacking enforced schemas.

Where should I store prompts?

Commit prompt snippets in your repo (docs/) so regenerations stay consistent across PRs.
