A range Bar chart

This is a floating Bar chart that could be used in order to indicate a range of sorts. It's actually a regular stacked Bar chart but just has the first color set to transparent. The background color has been set to a gradient going from white to slightly gray.

This goes in the documents header:
<script src="RGraph.svg.common.core.js"></script>
<script src="RGraph.svg.bar.js"></script>
Put this where you want the chart to show up:
<div id="chart-container" style="600px; height: 250px; display: inline-block"></div>
This is the code that generates the chart:
    data = [[5,16],[8,12],[9,16],[8,12],[9,15],[5,18],[4,12],[3,16]];

    var bar = new RGraph.SVG.Bar({
        id: 'chart-container',
        data: data,
        options: {
            xaxisLabels: ['Quentin','Bob','Neil','Olga','Charles','Chris','Luis','Pete'],
            xaxisColor: 'gray',
            colors: ['transparent', 'gradient(red:#fdd)'],
            backgroundColor: 'Gradient(#ddd:white:white)',
            grouping: 'stacked',
            yaxis: false,
            backgroundGrid: false
