A 3D Rose chart

[No canvas support]

This goes in the documents header:
<script src="RGraph.common.core.js"></script>
<script src="RGraph.rose.js"></script>
Put this where you want the chart to show up:
<canvas id="cvs" width="800" height="400">
    [No canvas support]
</canvas>
This is the code that generates the chart:
<script>
    new RGraph.Rose({
        id: 'cvs',
        data: [[4,8,7],[6,5,8],[4,5,3],[4,9,8],[3,8,6],[4,6,3],[1,5,8]],
        options: {
            strokestyle: 'rgba(0,0,0,0)',
            margin: 7,
            variant: 'stacked3d',
            variantThreedDepth: 10,
            labelsAxes: 'n',
            colors: ['gradient(#faa:red)','Gradient(#afa:green)','gradient(#aaf:#ddf)'],
            labels: ['Monday','Tuesday','Wednesday','Thursday','Friday','Saturday','Sunday'],
            textAccessible: false
        }
    }).draw();
</script>
