Most browsers will ignore the trailing comma, but it will break under IE.

You may also need to delay instantiating any dygraphs until after the DOM + content is ready, as there have been some reports + that excanvas won't work until this happens. If you're using jQuery, this + means drawing your charts inside of a $(function() { ... }) + block.
