[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="600" height="250">
    [No canvas support]
</canvas>
This is the code that generates the chart:
<script>
    new RGraph.Pie({
        id: 'cvs',
        data: [8,6,4,8,7,5],
        options: {
            labels: ['Mon','Tue','Wed','Thu','Fri','Sat','Sun'],
            textAccessibleOverflow: 'hidden'
        }
    }).grow();
</script>
