// As you will see the main routine ( doGet() ) uses the method
// GraphData() to construct the return data.
// Although in this example the GraphData() rountine simply builds the return
// data from 'hard coded' values, in practice this rountine would be expanded
// to first gather data from any number of datasources.
// eg. databases, files other server processes.
