Your first chart: JavaScript Data Grid Demo

A chart from the grid's own data in six lines

createChart({ grid, container, type, x, y })

This draws a chart from the grid's own data in six lines: hand it the grid, a container, a type, and the fields for the axes. It is the smallest start for charting, so you can see a live chart wired to real rows before learning anything more.
