/**
* Class: $.jqplot.BubbleRenderer
* Plugin renderer to draw a bubble chart. A Bubble chart has data points displayed as
* colored circles with an optional text label inside. To use
* the bubble renderer, you must include the bubble renderer like:
*
* > <script language="javascript" type="text/javascript" src="../src/plugins/jqplot.bubbleRenderer.js"></script>
*
* Data must be supplied in
* the form:
*
* > [[x1, y1, r1, <label or {label:'text', color:color}>], ...]
*
* where the label or options
* object is optional.
*
* Note that all bubble colors will be the same
* unless the "varyBubbleColors" option is set to true. Colors can be specified in the data array
* or in the seriesColors array option on the series. If no colors are defined, the default jqPlot
* series of 16 colors are used. Colors are automatically cycled around again if there are more
* bubbles than colors.
*
* Bubbles are autoscaled by default to fit within the chart area while maintaining
* relative sizes. If the "autoscaleBubbles" option is set to false, the r(adius) values
* in the data array a treated as literal pixel values for the radii of the bubbles.
*
* Properties are passed into the bubble renderer in the rendererOptions object of
* the series options like:
*
* > seriesDefaults: {
* > renderer: $.jqplot.BubbleRenderer,
* > rendererOptions: {
* > bubbleAlpha: 0.7,
* > varyBubbleColors: false
* > }
* > }
*
