This goes in the documents header:
<pre class="code">
<script src="RGraph.common.core.js"></script>
<script src="RGraph.common.effects.js"></script>
<script src="RGraph.common.dynamic.js"></script>
<script src="RGraph.drawing.text.js"></script>
<script src="RGraph.bar.js"></script>
</pre>
Put this where you want the chart to show up:
<pre class="code">
<canvas id="cvs" width="600" height="250">
[No canvas support]
</canvas>
</pre>
This is the code that generates the chart:
