A black and orange SVG Horizontal Bar chart

This is a Horizontal Bar chart that is actually made up of two charts. The first chart is the gray backgrounds for the bars that you can see. Then the orange Horizontal Bar chart is overlaid on top. The labels on the right are made up from the labelsAbove option (on the first background HBar chart). As you can see the chart uses the Wave effect (the wave effect is not just a Bar chart effect but also available with the Horizontal Bar chart.).

By combining charts like this you can get a multitude of different effects that just wouldn't be feasible with just a single chart. You can eamine the source code for both of the charts below. The DIV tag that the chart uses is itself wrapped in another DIV tag and its this one that has CSS applied to it.

This goes in the documents header:
<script src="RGraph.svg.common.core.js"></script>
<script src="RGraph.svg.hbar.js"></script>
Put this where you want the chart to show up:
<div style="padding: 15px">
    <div style="width: 500px; height: 300px; float: right" id="chart-container"></div>
</div>
This is the code that generates the chart:
<script>
    data   = [70,80,60,50,40,80];
    labels = ['JavaScript','HTML','CSS','React','Ruby','Python'];

    new RGraph.SVG.HBar({
        id: 'chart-container',
        data: [1,1,1,1,1,1],
        options: {
            colors: ['gray'],
            xaxisScale: false,
            backgroundGrid: false,
            vmargin: 5,
            yaxisLabels: labels,
            textColor: 'rgba(0,0,0,0)',
            labelsAbove: true,
            labelsAboveColor: 'white',
            labelsAboveSpecific: data
        }
    }).draw();

    new RGraph.SVG.HBar({
        id: 'chart-container',
        data: data,
        options: {
            colors: ['orange'],
            textColor: 'white',
            yaxisLabels: labels,
            xaxisScale: false,
            backgroundGrid: false,
            vmargin: 5
        }
    }).wave();
</script>
