Built in CSV support/Separate data from config
Please add "native" support for data as CSV. Partially in docs you describe how to make use of CSV data, but I think this is just too inconvenient. A nicer approach would be to have the API separate the "data to display" from the "configuration of a chart", where the data would be as CSV and the configuration as JSON or XML. Take a look at AnyCharts (or better AnyStock) for a very nice API that does this.
