I think I just stopped my train of thought and hit reply. I meant to point out that Charts.css relies on having <table> elements in the HTML. Vega relies purely on JSON. This may or may not be of concern. For instance, if you care about bots crawling the website for semantic information, then perhaps the Charts.css way of operating on top of <table>s is preferred. A minor point though.
