Nice; animated transitions are great for maintaining continuity when data is changing. Handling changes in the y-scale can be another source of distraction, so it's nice if you're able to fix the domain (as [0,1] in your example).
In January, I wrote a tutorial on how to implement this sort of real-time graph in D3.js, using transform transitions. (Don't get distracted by the top example; it's intentionally wonky.)
