A circular thumbnail demonstration
</div>
<h1>RGraph: <span>HTML5 Javascript charts library</span> - A circular thumbnail demonstration</h1>
<script>
if (RGraph.isIE8()) {
document.write('<div style="background-color: #fee; border: 2px dashed red; padding: 5px"><b>Important</b><br /><br /> Internet Explorer 8 does not natively support the HTML5 canvas tag, so if you want to see the charts, you can either:<ul><li>Install <a href="http://code.google.com/chrome/chromeframe/">Google Chrome Frame</a></li><li>Use ExCanvas. This is provided in the RGraph Archive.</li><li>Use another browser entirely. Your choices are Firefox 3.5+, Chrome 2+, Safari 4+ or Opera 10.5+. </li></ul> <b>Note:</b> Internet Explorer 9 fully supports the canvas tag.</div>');
}
</script>
<canvas id="cvs" width="600" height="250" style="float: right">[No canvas support]</canvas>
<script>
var line = new RGraph.Line('cvs', [5,3,4,6,5,1,3,4,5,5], [4,8,6,7,4,3,5,1,2,3]);
line.Set('chart.colors', ['red', 'black']);
line.Set('chart.hmargin', 5);
line.Set('chart.linewidth', 5);
line.Set('chart.shadow', true);
line.Set('chart.shadow.offsetx', 0);
line.Set('chart.shadow.offsety', 0);
line.Set('chart.shadow.blur', 15);
line.Set('chart.shadow.color', ['red','black']);

</script>
<p>
This is a demonstration of the zoom in thumbnail mode with some custom CSS (the <i>border-radius</i> property) which facilitates
making the thumbnail circular.
</p>
<p>
Remember that browser support for this is limited - currently (5th September 2011) only Firefox 4+ and IE9+ support it.
