I noticed that the example for a real time updating graph (go to http://krispo.github.io/angular-nvd3/#/quickstart -> examples -> Other examples in Plunker -> "Real-time chart updating") causes a quite high CPU load for the Chrome process on my MacBook, around 50%.
I think this is quite high - is there any optimization potential? Is there any way around this issue? Reason is that my web app became less responsive after I played with a real time updating graph and I suspect that the framework isn't suitable for my needs.
