Overview

VegaFusion provides Rust, Python, and JavaScript libraries for analyzing and scalingVega visualizations. The goal is to provide low-level building blocks that higher level Vega systems (such asVega-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.

Python Installation

The VegaFusion Python package can be installed into a Python environment using pip

pip install vegafusion

or conda

conda install -c conda-forge vegafusion

Documentation
