A basic Meter chart

[No canvas support]

This goes in the documents header:
<script src="RGraph.common.core.js"></script>
<script src="RGraph.meter.js"></script>
Put this where you want the chart to show up:
<canvas id="cvs" width="600" height="300">
    [No canvas support]
This is the code that generates the chart:
    new RGraph.Meter({
        id: 'cvs',
        min: 0,
        max: 100,
        value: 45,
        options: {
            colorsGreenColor: 'Gradient(green:#040)',
            colorsYellowColor: 'Gradient(#ff0:#440)',
            colorsRedColor: 'Gradient(#f00:#400)',
            labelsValueText: true,
            labelsValueTextUnitsPost: ',000k'
