Altair: A declarative statistical visualization library for Python.

http://altair-viz.github.io/

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.

Please note that if you wish to use altair in the Jupyter Notebook, the ipyvega_ notebook extension must be enabled as follows::

$ pip install altair
$ pip install --upgrade notebook
$ jupyter nbextension install --sys-prefix --py vega
