A basic Radial Scatter chart

[No canvas support]

This goes in the documents header:
<script src="RGraph.common.core.js"></script>
<script src="RGraph.rscatter.js"></script>
Put this where you want the chart to show up:
<canvas id="cvs" width="500" height="500">
    [No canvas support]
</canvas>
This is the code that generates the chart:
<script>
    for (var i=0,data = []; i<360; i+=2) {
        data.push([i*2, i, 'red']);
    }

    new RGraph.RScatter({
        id: 'cvs',
        data: [data],
        options: {
        }
    }).draw();
</script>
