Support for explorercanvas
This version adds support for explorercanvas.
I've had a few questions before about compatibility with IE8. There are javascript libraries that (try) to add canvas support to older browsers, but after actually trying to use one of them myself I found that it certainly did not work "out of the box". I made a number of changes in TimeCircles so that no special tricks or changes need to be made anymore in order to make TimeCircles work with explorercanvas.
So, as of right now, if you want TimeCircles to function in IE 8, download explorercanvas:

Then you can simply add:
<!--[if lt IE 9]>
<script type="text/javascript" src="path/excanvas.js"></script>
<![endif]-->
In the head of your page. Do keep in mind, you'll have to change the path to match where you have placed the file.
