    /**
     * Class: $.jqplot.FunnelRenderer
     * Plugin renderer to draw a funnel chart.
     * x values, if present, will be used as labels.
     * y values give area size.
     * 
     * Funnel charts will draw a single series
     * only.
     * 
     * To use this renderer, you need to include the 
     * funnel renderer plugin, for example:
     * 
     * > <script type="text/javascript" src="plugins/jqplot.funnelRenderer.js"></script>
     * 
     * Properties described here are passed into the $.jqplot function
     * as options on the series renderer.  For example:
     * 
     * > plot2 = $.jqplot('chart2', [s1, s2], {
     * >     seriesDefaults: {
     * >         renderer:$.jqplot.FunnelRenderer,
     * >         rendererOptions:{
     * >              sectionMargin: 12,
     * >              widthRatio: 0.3
     * >          }
     * >      }
     * > });
     * 
     * IMPORTANT
     * 
     * *The funnel renderer will reorder data in descending order* so the largest value in
     * the data set is first and displayed on top of the funnel.  Data will then
     * be displayed in descending order down the funnel.  The area of each funnel
     * section will correspond to the value of each data point relative to the sum
     * of all values.  That is section area is proportional to section value divided by 
     * sum of all section values.
     * 
     * If your data is not in descending order when passed into the plot, *it will be
     * reordered* when stored in the series.data property.  A copy of the unordered
     * data is kept in the series._unorderedData property.
     * 
     * A funnel plot will trigger events on the plot target
     * according to user interaction.  All events return the event object,
     * the series index, the point (section) index, and the point data for 
     * the appropriate section. *Note* the point index will referr to the ordered
     * data, not the original unordered data.
     * 
     * 'jqplotDataMouseOver' - triggered when mousing over a section.
     * 'jqplotDataHighlight' - triggered the first time user mouses over a section,
     * if highlighting is enabled.
     * 'jqplotDataUnhighlight' - triggered when a user moves the mouse out of
     * a highlighted section.
     * 'jqplotDataClick' - triggered when the user clicks on a section.
     * 'jqplotDataRightClick' - tiggered when the user right clicks on a section if
     * the "captureRightClick" option is set to true on the plot.
