LONG_DESCRIPTION = """
This package provides a Python API for building statistical visualizations in a
declarative manner. This API contains no actual visualization rendering code, but
instead emits JSON data structures following the `Vega-Lite`_ specification. For
convenience, Altair can optionally use `ipyvega`_ to seamlessly display client-side
renderings in the Jupyter notebook.

Visit our GitHub repository (https://github.com/ellisonbg/altair) for
installation instructions, examples and documentation.
