While I love this article as it teaches many great things about canvas, I would suggest trying for better text within the canvas element. That text is what is sent to assistive technology, not just older versions of IE that don’t support canvas.
For this particular tutorial I do not have a better suggestion. But something like that should be kept in mind. A lot of times I’ve developed canvas stuff to show graphs and including an HTML table inside listing tabular data is a good fallback.
