Visualize graph not working in Explorer 8 Object doesn't support this property or method #72

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
Using Firefox or Opera everything seems to work fine. The problem is with IE8 
and the error it throws me is "Object doesn't support this property or method". 
And the location of the error is in two different places: jquery-1.6.4.min.js 
line 2 character 15738. The other is visualize.jQuery.js line 446 character 3. 
Specifically, it highlights this:

var ctx = canvas[0].getContext('2d');

The page itself is pretty straightforward and here is it, here:
