VegaFusion provides Rust, Python, and JavaScript libraries for analyzing and scaling Vega visualizations. The goal is to provide low-level building blocks that higher level Vega systems (such as Vega-Altair in Python) can integrate with.
Note
If you've arrived here looking for information on how to scale Vega-Altair visualizations to support larger datasets,
see the Vega-Altair documentation on the "vegafusion" data transformer.
The VegaFusion Python package can be installed into a Python environment using pip
pip install vegafusionor conda
conda install -c conda-forge vegafusionSee Documentation and Examples.
