Needed dependencies
-------------------

pygal uses `lxml <http://lxml.de/>`_ to generate the svg, this is the only needed dependency.

Optional dependencies
---------------------

PNG output requires `CairoSVG <http://cairosvg.org/>`_, `tinycss <http://packages.python.org/tinycss/>`_ and `cssselect <http://packages.python.org/cssselect/>`_.
Install those with ``pip install CairoSVG tinycss cssselect``.

Interpolations need the `scipy <http://www.scipy.org/>`_ python module.

Unit testing needs `py.test <http://pytest.org/latest/>`_ or `nosetests <http://readthedocs.org/docs/nose/en/latest/>`_.

Visual testing is based on `flask <http://flask.pocoo.org/>`_.
