Perl helper class for the Google Chart Tools Datasource Protocol
The Google Visualization API is a nifty bit of kit for generating pretty pictures from your data. By design it has a fair amount of Google-cruft, such as non-standard JSON and stuffing configuration options in to a single CGI query parameter. It’s also got somewhat confusing documentation, and some non-obvious rules for generating certain message classes.
DataGoogleVisualizationDataTable takes care of preparing data for the API, but this module implements the Google Chart Tools Datasource Protocol, or Google Visualization API wire protocol, or whatever it is they’ve decided to call it this week.
