A Semi-circular Progress chart showing multiple values

[No canvas support]

This goes in the documents header:
<script src="/libraries/RGraph.common.core.js"></script>
<script src="/libraries/RGraph.common.dynamic.js"></script>
<script src="/libraries/RGraph.common.tooltips.js"></script>
<script src="/libraries/RGraph.common.key.js"></script>
<script src="/libraries/RGraph.semicircularprogress.js"></script>
Put this where you want the chart to show up:
<canvas id="cvs" width="600" height="300">
    [No canvas support]
</canvas>
This is the code that generates the chart - it should be placed AFTER the canvas tag(s):
