		<![CDATA[This Pie Chart uses a custom renderer to render its wedges with 'threshold' colors. Meaning values greater than
80 are red, greater than 50 are yellow, and all others are green. The demo isn't that exciting, but it's a good example
of how to write a custom renderer that does something quantitative with the data it's representing. WHile this demo only
includes a Wedge Renderer for pie charts, the code is written to be reusable, meaning the colors and threshold values
can be specified when using the renderer, and the source can be easily used to write threshold renderers for other 
chart types.<br/>
