Absolutely. This shines when you actually want to display complex / animated / streaming data in larger applications; or if you want to create educative or training material on several pages (i.e apps here).
As an example, I once built an online stock/ticker app with it: smooth real-time updates in a nice plot. It would have been more complex with DOM based widgets (and probably less fun).
