It's hard to do anything DOM based at 60FPS and a moderate number of points, if that is the main crux of your problem then I think you picked the correct route (custom D3). Still I find it's hard not to rinse peoples CPU in the browser when doing this.

Alternatively if you have nore than 10K points it's probably time to abandon DOM based methods and just redraw everything every frame directly (canvas / webgl).
