An adjustable Semi-circular Progress chart

[No canvas support]

This goes in the documents header:
<script src="RGraph.common.core.js"></script>
<script src="RGraph.common.dynamic.js"></script>
<script src="RGraph.semicircularprogress.js"></script>
Put this where you want the chart to show up:
<canvas id="cvs" width="300" height="200">
    [No canvas support]
This is the code that generates the chart:
    new RGraph.SemiCircularProgress({
        id: 'cvs',
        min: 0,
        max: 100,
        value: 83,
        options: {
            marginTop: 10,
            marginLeft: 10,
            marginRight: 10,
            adjustable: true,
            scaleUnitsPost: '%',
            textAccessiblePointerevents: false,
            colors: ['Gradient(white:#0a0)']
