Diagrams as Code
Generate architecture and infrastructure diagrams using the Python diagrams library. Diagrams are Python scripts that render to image files via Graphviz.
Workflow
- Check prerequisites - verify graphviz and diagrams are installed
- Write the diagram script to a
.pyfile in the user's working directory - Run it with
python3 <file>.py - Report the output path to the user (image appears in working directory)
Prerequisites check
command -v dot >/dev/null || brew install graphviz
uv pip install --system diagrams 2>/dev/null || pip install diagrams
Without graphviz, the script fails with a cryptic error. Always verify first.
