EEA Daviz product
=================
EEA Daviz is a plone product for data visualizations. You can generate attractive 
and interactive charts and combine them in a dashboard with facets/filters 
which updates the charts simultaneously. Data can be uploade as CSV,TSV or you can 
specify SPARQL to query Linked open data servers (sparql endpoints). 

At the moment Simile Exhibit and Google Charts visualizations are supported. 

The first Semantic web data visualisation tool for Plone.

Installation
============

To install eea.daviz into the global Python environment (or a workingenv),
using a traditional Zope 2 instance, you can do this:

 * When you're reading this you have probably already run
   ``easy_install eea.daviz``. Find out how to install setuptools
   (and EasyInstall) here:
   http://peak.telecommunity.com/DevCenter/EasyInstall

 * If you are using Zope 2.9 (not 2.10), get `pythonproducts`_ and install it
   via::

       python setup.py install --home /path/to/instance

   into your Zope instance.

 * Create a file called ``eea.daviz-configure.zcml`` in the
   ``/path/to/instance/etc/package-includes`` directory.  The file
   should only contain this::

       <include package="eea.daviz" />

.. _pythonproducts: http://plone.org/products/pythonproducts


Alternatively, if you are using zc.buildout and the plone.recipe.zope2instance
recipe to manage your project, you can do this:

  * Add ``eea.daviz`` to the list of eggs to install, e.g.::

      [buildout]
      eggs = eea.daviz

  * Tell the plone.recipe.zope2instance recipe to install a ZCML slug::

      [instance]
      recipe = plone.recipe.zope2instance
      zcml = eea.daviz

  * Re-run buildout, e.g. with::

      $ ./bin/buildout

You can skip the ZCML slug if you are going to explicitly include the package
from another package's configure.zcml file.
