A(nother) nested Donut/Pie chart

[No canvas support]

This goes in the documents header:
<script src="RGraph.common.core.js"></script>
<script src="RGraph.drawing.text.js"></script>
<script src="RGraph.pie.js"></script>
Put this where you want the chart to show up:
<canvas id="cvs" width="475" height="350" >
    [No canvas support]
</canvas>
This is the code that generates the chart:
<script>
    centerx = 170;

    pie1 = new RGraph.Pie({
        id: 'cvs',
        data: [1,1,1,1,1,1],
        options: {
            colors: ['#0096A0','#0096A0','#FDA72A','#FDA72A','#0096A0','#0096A0'],
            variant: 'donut',
            radius: 125,
            centerx: centerx,
            variantDonutWidth: 20,
            linewidth: 2,
            exploded: [,25], // Just explode the second segment
            strokestyle: 'white',
            shadow: false
        }
    }).roundRobin(null, function ()
    {
        var pie2 = new RGraph.Pie({
            id: 'cvs',
            data: [1,1,1,1,1,1],
