       * 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.
