eea.app.visualization 4.1

Visualization API

EEA App Visualisation is the Core API for EEA Daviz. This package was added in order to be able to use EEA Google Charts without EEA Exhibit and viceversa or any other visualization library as a standalone visualization or as part of a bundle package (eea.daviz)

The following graph show the arhitecture of EEA Visualisation:

 -------------------------------------------------------------------------

This package as standalone is just an API, you have to either install eea.daviz bundle, either install one of the available visualization libraries (eea.exhibit, eea.googlecharts, etc) in order to have a working Visualization Tool for your files.

Installation

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

• Add eea.app.visualization to the list of eggs to install, e.g.:

  [buildout]
  eggs = eea.app.visualization

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

  [instance]
  recipe = plone.recipe.zope2instance
  zcml = eea.app.visualization

• 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.
