Mosaic Widget
A Jupyter widget for Mosaic. Given a declarative specification, will generate web-based visualizations while leveraging DuckDB in the Jupyter kernel. Create interactive Mosaic plots over Pandas and Polars data frames or DuckDB connections.
Learn how to install and use the widget in the Mosaic documentation.
Developer Setup
We use uv to manage our development setup.
You can start Jupyter with ANYWIDGET_HMR=1 uv run jupyter lab --notebook-dir=../../../dev/notebooks.
Run pnpm build to build the widget JavaScript code. If you want to live edit the widget code, run pnpm dev in a separate terminal.
Run uv run ruff check --fix and uv run ruff format to lint the code.
Publishing
Run the build with uv build. Then publish with uvx twine upload --skip-existing ../../dist/*. We publish using tokens so when asked, set the username to __token__ and then use your token as the password. Alternatively, create a .pypirc file.
