Firstly, great job on this repo. Can't wait for it to get better. I'm currently trying to use this module to use a line graph for my ECG data and animate it with new data. Is it possible to use real-time data and show it in a line graph? Here is what I mean by [`animation`](http://joakimkemeny.github.io/jke.d3.ecg/). Please let me know. Thanks
