// Basic requirements for creating a bar chart in a JSP page:
//   1) Create a BarChart instance and a data-source 
//   2) Create a data model and attach the data source to it
//   3) Assign the Category variable role, and optionally the
//      Response variable role, to appropriate variable(s)
//   4) Assign the data model to the BarChart
//   5) Set HTTP-specific response and request functionality
// To set a title or footnote, get the appropriate BarChart
// title or footnote, and then set the returned object's text.
