A basic Pie chart

This goes in the documents header:

<script src="RGraph.common.core.js"></script>
<script src="RGraph.common.dynamic.js"></script>
<script src="RGraph.common.tooltips.js"></script>
<script src="RGraph.pie.js"></script>

Put this where you want the chart to show up:

<canvas id="cvs" width="550" height="300">
    [No canvas support]
</canvas>

This is the code that generates the chart:

<script>
    data     = [41.2,18.2,17.2,14.2,5,4.2];
    labels   = ['Symbian','Blackberry','Android','iOS','Windows','Others'];
    tooltips = [];
    
    labels.forEach(function (v, k, arr)
    {
        tooltips[k] = '<b>{1}</b><br /><br /><i>Market share: {2}%</i>'.format(
            labels[k],
            data[k]
        );
        
        labels[k] = labels[k] + ' ' + data[k] + '%';
    });


    pie = new RGraph.Pie({
        id: 'cvs',
        data: data,
        options: {
            tooltips: tooltips,
            labels: labels,
            labelsBold: true,
            labelsSticks: true,
            labelsSticksLength: 45,
            labelsSticksUsecolors: false,
            shadow: false,
            strokestyle: 'rgba(0,0,0,0)',
            colors: ['#F0F0F0','#08306B','#D9D9D9','#BDBDBD','#969696','#D9D9D9'],
            textFont: '"Lucida Grande", "Lucida Sans Unicode", Arial',
            textSize: 10,
            textColor: 'black',
            labelsColors: ['black'],
            tooltipsEvent: 'mousemove',
            highlightStyle: 'outline',
            title: 'Smartphone share in Q2 2010',
            titleY: -25,
            titleSize: 18,
            gutterTop: 50
        }
    }).roundRobin();
    
    // Align the tooltip text to the left
    RGraph.tooltips.style.textAlign = 'left';
</script>
