A single web page Bar chart example which has inlined the RGraph libraries

[No canvas support]
Put this at the BOTTOM of the page
<script>
    // Put the source code of the RGraph.common.core.js file
    // here - all 10,000+ lines of it.
</script>

<script>
    // Put the source code of the RGraph.bar.js file
    // here.
</script>
Put this where you want the chart to show up:
<div style="display: inline-block; margin: 35px">
    <canvas id="cvs" width="600" height="300">[No canvas support]</canvas>
</div>
This is the code that generates the chart - it uses the window.onload event so you can put it anywhere:
<script>
    window.onload = function ()
    {
        new RGraph.Bar({
            id: 'cvs',
            data: [45,23,56,15,58,59,45],
            options: {
                xaxisLabels: ['Jill','Joseph','Joe','Jim','July','Jake','John'],
                textSize: 20,
                backgroundGridVlines: false,
                backgroundGridBorder: false,
                xaxis: false,
                yaxis: false
            }
        }).draw();
    };
</script>
