Drupal install profile with modules for creating graphs and charts with the help of Charts and Graphs API . Also comes with search API graphing modules (when we are done).
Charts Graphs supports rendering graphs by different libraries.
If you want to see the full power of the graphing (and mapping) stack, there is a feature included in dgraphs that enables the use of search_api and solr.
We'll soon have a download on http://www.dgraphs.com but for now you can also install using drush:
drush make http://drupalcode.org/project/dgraphs.git/blob_plain/HEAD:/build-dgraphs.make
