Demo - Using a Graph Element to make Bar Charts

The Graph Element is very versatile. Because you can define your own

coordinate system, it makes producing graphs of many lines (bar, line, etc) very

straightforward.

In this Demo a "bar" is nothing more than a rectangle drawn in a Graph Element (draw_rectangle).

To make things a little more interesting, this is a barchart with that data values

placed as labels atop each bar, another Graph element method (draw_text)
