EEA Daviz is a web tool developed by the European Environment Agency which helps creating interactive data visualizations easily through the web browser, no extra tools are necessary. It is free and open source.

Within ZMI -> Plone Site -> portal_properties add a plone property sheet called geographical_properties and inside it add a new string property called google_key.
Within ZMI -> Top Folder -> manage_propertiesForm add a string property called google_key
The Google account you use to generate the key has to be owner of the site, this is done by verification via Google webmaster tools.
