Pie chart RoundRobin then Explode

This goes in the documents header:

<script src="RGraph.common.core.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="450" height="300">
    [No canvas support]
</canvas>

This is the code that generates the chart:

<script>
    window.onload = function ()
    {
        var pie = new RGraph.Pie({
            id: 'cvs',
            data: [4,3,5,1,2],
            options: {
                linewidth: 0,
                strokestyle: 'rgba(0,0,0,0)',
                
            }
        }).roundRobin(null, function () {pie.explodeSegment(0, 20);});
    };
</script>
