You can have as many columns of data as you like (well, within the limits of what javascript can reasonably handle, but for all intents and purposes, it is effectively unlimited). Not all charts can use an arbitrary number of columns, though. Some (like GeoCharts, require specific column layouts in order to function properly. If you need to have more columns of data, but don't intend to use them in a particular chart, then you can filter them out using a DataView or the "view" parameter of a ChartWrapper.
