A Pie chart using the roundRobin() effect

[No canvas support]

This goes in the documents header:
<script src="RGraph.common.core.js"></script>
<script src="RGraph.common.dynamic.js"></script>
<script src="RGraph.common.tooltips.js"></script>
<script src="RGraph.common.effects.js"></script>
<script src="RGraph.pie.js"></script>
Put this where you want the chart to show up:
<canvas id="cvs" width="400" height="300">
    [No canvas support]
This is the code that generates the chart:
    new RGraph.Pie({
        id: 'cvs',
        data: [4,3,5,1,2],
        options: {
            linewidth: 0,
            colorsStroke: 'rgba(0,0,0,0)',
    }).roundRobin(null, function () {pie.explodeSegment(0, 20);});
