Charts with no grid on screen: JavaScript Data Grid Demo
The data engine driving charts on its own
createHeadlessGrid
This drives charts from the data engine alone, with no grid on screen. It shows that the charting and the data model do not need a visible table, so you can chart a dataset headlessly.
