Visualize a pipeline

Status: Available in ETLantic 0.53.0 (Beta release candidate). After Quickstart.

Python

from pathlib import Path

# SamplePipeline is the class from etlantic init (pipeline.py).
diagram = SamplePipeline.to_mermaid()
Path("pipeline.mmd").write_text(diagram, encoding="utf-8")

to_mermaid() uses the logical graph only. It does not plan or execute.

CLI

From the Quickstart project:

python -m etlantic viz dot pipeline.py:SamplePipeline
python -m etlantic viz html pipeline.py:SamplePipeline -o lineage.html
python -m etlantic viz lineage pipeline.py:SamplePipeline --format json

viz lineage is read-only stdout. viz html always writes a file. Details: Mermaid and CLI — viz.
