A node graph workflow is a visual programming pattern — most prominently ComfyUI, n8n, Make, LangGraph — where a pipeline is built as connected nodes that pass data along edges.

Node graphs make complex pipelines reproducible and shareable. In AI image generation (ComfyUI), node graphs compose Stable Diffusion, ControlNet, IP-Adapter, LoRAs, upscalers, post-processing — and the whole pipeline is a JSON blob you can version, share, and replay. In AI workflow automation (n8n, Make), node graphs replace fixed scripts with visual branching. In agentic systems (LangGraph), node graphs are the state-machine representation of the agent. The advantage: each node has narrow responsibility; the pipeline is debuggable end-to-end; reproducibility is built in. The cost: learning curve.

## When to use

- Complex production pipelines that benefit from explicit composition.
- Reproducible AI image / video pipelines.
- Agentic workflows with branching.

## Common mistakes

- Over-decomposing a simple pipeline into too many small nodes.
- Skipping documentation — node graphs need labels to remain readable.
