An inverted Funnel chart showing a hypothetical company structure

[No canvas support]

This goes in the documents header:
<script src="RGraph.common.core.js"></script>
<script src="RGraph.funnel.js"></script>
Put this where you want the chart to show up:
<canvas id="cvs" width="450" height="500">
    [No canvas support]
</canvas>
This is the code that generates the chart:
<script>
    new RGraph.Funnel({
        id: 'cvs',
        data: [15,26,54,84,100, 186],
        options: {
            labels: ['Directors','Regional directors', 'Regional Managers','Managers','Supervisors','Programmers'],
            labelsSticks: true,
            labelsX: 5,
            marginLeft: 230,
            colorsStroke: 'rgba(0,0,0,0)',
            textBoxed: false,
            shadow: true,
            shadowOffsetx: 0,
            shadowOffsety: 0,
            shadowBlur: 15,
            shadowColor: 'gray',
            colors: ['red','green','blue','pink','#666']
        }
    }).draw();
</script>
