We need to load Google's JS.

load_params¶
Load the "packages" required for the visualization; define a
"packages_to_load" method which returns a list of them.
render_data¶
Renders the columns and the data.
add_columns¶
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.
add_data¶
Adds the data to the chart. Each data point should be a hash reference of column
id to value.
