An SVG grouped Bar chart

This is a grouped Bar chart that has an offset X axis and also uses the grow() effect and a key so that you can differentiate the different colored bars.

This goes in the documents header:
<script src="RGraph.svg.common.core.js"></script>
<script src="RGraph.svg.common.key.js"></script>
<script src="RGraph.svg.bar.js"></script>
Put this where you want the chart to show up:
<div style="padding: 15px">
    <div style="width: 750px; height: 300px" id="chart-container"></div>
</div>
This is the code that generates the chart:
