A Donut chart showing browser market share

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.key.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>
    window.onload = function ()
    {
        var donut = new RGraph.Pie({
            id: 'cvs',
            data: [41,37,16,3,3],
            options: {
                variant: 'donut',
                linewidth: 5,
                exploded: 5,
                strokestyle: 'rgba(0,0,0,0)',
                title: "Browser share",
                tooltips: ['MSIE 7 (41%)', 'MSIE 6 (37%)', 'Firefox (16%)', 'Safari (3%)', 'Other (3%)'],
                key: ['MSIE 7 (41%)', 'MSIE 6 (37%)', 'Firefox (16%)', 'Safari (3%)', 'Other (3%)'],
                keyShadow: true,
                keyShadowOffsetx: 1,
                keyShadowOffsety: 1,
                keyShadowBlur: 3,
                keyShadowColor: '#ccc',
                keyAlign: 'right',
                align: 'left',
                shadowOffsetx: 2,
                shadowOffsety: 2,
                shadowBlur: 3,
                centerx: 185
            }
        }).draw();
    };
</script>
