Jifty::Plugin::Chart::Renderer::GoogleViz - chart renderer using Google Charts JS

We need to load Google's JS.

Load the "packages" required for the visualization; define a packages_to_load method which returns a list of them.

Renders the columns and the data.

Adds the columns to the visualization. Each column is a key-value pair; the key is the column's id and the value is either a string (the type) or a hashref. The hashref may specify type and label. If no label is given, the id is used.

It will return a hashref of canonicalized columns.

Adds the data to the chart. Each data point should be a hash reference of column id to value.
