A Meter chart customised to look a bit like the Google charts Meter

[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.meter.js"></script>
Put this where you want the chart to show up:
<canvas id="cvs" width="600" height="250" style="border-radius: 15px">
    [No canvas support]
This is the code that generates the chart:
    new RGraph.Meter({
        id: 'cvs',
        min: 0,
        max: 100,
        value: 75,

            anglesStart: RGraph.PI + 0.5,
            anglesEnd: RGraph.TWOPI - 0.5,
            linewidthSegments: 0,
            textSize: 16,
            colorsStroke: 'white',
