jupyterlab_drawio_render_extension
View Draw.io diagrams directly in JupyterLab. Open any .drawio or .dio file and see it rendered with full fidelity - text, shapes, stencils, icons, and styles matching the official Draw.io application.
This extension uses the official Draw.io viewer library from jgraph, served locally from the server extension for offline capability and CSP compliance.
Features
- Full Draw.io rendering - Uses official Draw.io viewer library for pixel-perfect diagram display
- Read-only viewer - Safe viewing without accidental modifications
- Interactive controls - Scroll to zoom, drag to pan, layers panel, and lightbox view
- PNG export - Right-click to copy or download diagram as PNG with configurable DPI
- Configurable background - Choose from default (theme), black, white, or custom hex color
- Full stencil support - Veeam, Cisco, AWS, Azure, GCP, and all vendor shapes
- Offline capable - Viewer library served locally, no external network requests
- JupyterLab 4 compatible - Built for the latest JupyterLab release
PNG Export
Right-click on any diagram to access export options:
- Copy Diagram as PNG - Copy to clipboard at configured DPI
- Download Diagram as PNG - Save as PNG file
Export automatically crops to diagram content with minimal padding.
Agent skill and CLI
The package ships the jupyterlab-drawio CLI with four subcommands: shapes searches the official palette and stencil shapes, stencils lists the stencil sets, validate lints a .drawio file, and layout lays out a graph JSON with Graphviz.
The agent skill lives in the repository at .agents/skills/jupyterlab-drawio-render-extension/ and is installed to share/jupyter/agents/skills/jupyterlab-drawio-render-extension/. No agent reads share/jupyter/agents/skills, so link the installed copy into the directory your agent reads.
After pip install, with the Python that runs the lab:
mkdir -p ~/.agents/skills && ln -sfn "$(python -c 'import sys; print(sys.prefix)')/share/jupyter/agents/skills/jupyterlab-drawio-render-extension" ~/.agents/skills/jupyterlab-drawio-render-extension
From a clone:
mkdir -p ~/.claude/skills && ln -sfn "$PWD/.agents/skills/jupyterlab-drawio-render-extension" ~/.claude/skills/jupyterlab-drawio-render-extension
