I got a link from Ajaxian this morning to a cool new JQuery plug-in that allows you to produce Accessible charts from HTML Tables incredibly easily.

Using a single line: 

<code>$('table').visualize();
</code>

You get a nicely rendered chart added to your page.  The website for the plugin has all the details and a couple of examples for you to check out.  It looks very cool indeed and I’m adding it to my toolbox for sure :0)
