<script>
    new RGraph.Bar({
        id: 'cvs',
        data: [ [4,8,3],[5,2,1], [8,4,2],[3,6,1],[5,1,0],[2,5,1],[1,2,2] ],
        options: {
            variant: '3d', 
            strokestyle: 'rgba(0,0,0,0)',
            colors: ['Gradient(#fbb:red)', 'Gradient(#bfb:green)','Gradient(#bbf:blue)'],
            gutterBottom: 80,
            labels: ['Monday','Tuesday','Wednesday','Thursday','Friday','Saturday','Sunday'],
            shadowColor:'#ccc',
            shadowOffsetx: 3,
            backgroundGridColor: '#eee',
            variantThreedAngle: 0.1,
            axisColor: '#ccc'
        }
    }).draw();
</script>

As well as customising the charts to look how you want you can manipulate the data to show different kinds of things - such as the fan style Line chart showing deviation from a predicted set of values .
