Development - Add error bars to plots

Dear developers,

I recently came across these awesome graphs. I am a scientist and a key part of science is presenting data. 

Using html5 instead of powerpoint to make presentations can make them far more interactive. I am implementing your fantastic graphs in a presentation, however, for scientific purposes it is absolutely required that you have error bars in your graphs. It would simply be assigning a value to each data point that would define the size of the error bar. 

I am a rookie coder, and terrible at javascript, but is this something you would consider adding? This would be fantastic for the scientific community.
