An example of a Rose chart with an interactive key

The interactive key has been re-implemented as of June 2013 and added to more chart types.

[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.common.key.js"></script>
<script src="RGraph.drawing.rect.js"></script>
<script src="RGraph.bar.js"></script>
Put this where you want the chart to show up:
<canvas id="cvs" width="450" height="300">
    [No canvas support]
</canvas>
This is the code that generates the chart:
<script>
    window.onload = function ()
    {
        var rose = new RGraph.Rose({
            id: 'cvs', 
            data: [
                [3,2,5],
                [4,5,3],
                [5,6,4],
                [1,8,5],
                [4,5,3]
            ],
            options: {
                textAccessible: true,
                key: ['Richard','Dave','Charles'],
                keyInteractive: true,
                margin: 5,
                labelsAxes: []
            }
        }).draw();
    };
</script>
