An SVG Rose chart with unequal segment sizes

An example of the Rose chart where the segment sizes are unequal - thus allowing you to show an extra dimension of information.

This goes in the documents header:
<script src="RGraph.svg.common.core.js"></script>
<script src="RGraph.svg.common.tooltips.js"></script>
<script src="RGraph.svg.rose.js"></script>
Put this where you want the chart to show up:
<div style="width: 650px; height: 500px" id="chart-container"></div>
This is the code that generates the chart:
<script>
    rose = new RGraph.SVG.Rose({
        id: 'chart-container',
        data: [[56,5],[48,3],[81,2],[68,9],[45,9],[45,1],[12,3],[43,8],[65,2],[42,3]],
        options: {
            colorsStroke: 'white',
            linewidth: 3,
            variant: 'non-equi-angular',
            colorsSequential: true,
            colorsOpacity: 0.6,
            tooltips: ['Alf','Bert','Craig','Doug','Edgar','Fred','Gary','Harry','Indigo','Jack'],
            labels: ['Alf','Bert','Craig','Doug','Edgar','Fred','Gary','Harry','Indigo','Jack']
        }
    }).draw();
