com.google.visualization.datasource.render.JsonpRenderer

Takes a data table and returns a json string.

The renderer renders a response which primarily contains the serializing of a data table. The response type can be either json or jsonp (a json format wrapped inside a callback method). The main difference regarding data table serialization between the two types, is the way dates are serialized. Dates have no standard representation in json thus they are rendered according to the future use of the response. When the response type is jsonp, the data table is likely to be evaluated with standard browser 'eval' and therefore date represented by Date constructor will be transformed into javaScript dates (as expected), e.g new Date(2011,1,1). When the response type is json, Date constructors can not be used (not defined in the json standard) and so custom date strings are used instead. In this case, custom parsing of the string is required to construct dates objects from their respective strings, e.g "Date(2011,1,1)". @author Nimrod T.
