A Pie chart with a halo effect

[No canvas support]

This goes in the documents header:
<script src="RGraph.common.core.js"></script>
<script src="RGraph.pie.js"></script>
Put this where you want the chart to show up:
<canvas id="cvs" width="350" height="250">
    [No canvas support]
</canvas>
This is the code that generates the chart:
<script>
    labels = [ 'Alvin',  'Pete', 'Luka', 'Hoolio', 'Jack', 'Kev', 'Luis', 'Lou', 'Jesse' ];

    pie = new RGraph.Pie({
        id: 'cvs',
        name: 'cvs',
        data: [4,3,2,9,5,1,6,8,4],
        options: {
            shadow: false,
            linewidth: 5,
            labels: labels,
            labelsSticksColors: '#aaa',
            labelsSticksLinewidth: 1
        }
    }).on('draw', function(obj)
    {
        RGraph.path2(
            obj.context,
            'lw 5 b a % % % 0 6.2830 false s white',
            obj.centerx,
            obj.centery,
            obj.radius - 12
        );

    }).draw();
</script>
