    <h1>A Scatter chart with the ability to add markers</h1>
    
    <p>
        You can click on the Scatter chart to add a red circle. When the circles are then clicked on nothing happens.

    This goes in the documents header:
    <pre class="code">
&lt;script src="RGraph.common.core.js"&gt;&lt;/script&gt;
&lt;script src="RGraph.common.dynamic.js"&gt;&lt;/script&gt;
&lt;script src="RGraph.common.circle.js"&gt;&lt;/script&gt;
&lt;script src="RGraph.drawing.circle.js"&gt;&lt;/script&gt;
&lt;script src="RGraph.scatter.js"&gt;&lt;/script&gt;
</pre>
    
    Put this where you want the chart to show up:
    <pre class="code">
&lt;canvas id="cvs" width="600" height="200"&gt;
    [No canvas support]
&lt;/canvas&gt;
</pre>

    This is the code that generates the chart:
    <pre class="code">
&lt;script&gt;
    window.onload = function ()
