Honestly I did't know about plotly until recently, and now I definitely gonna use it.
In theory Zeppelin notebook can run any python code but in practice not in my case because I run it on Windows. As soon as I move all my stuff to some linux machine I will try. Also I'll try bokeh and mathplotlib.
I need something python-based, web-shared with maximum interactive stuff like filters, different slices (a-la excel pivot table) and so on. And I hate JavaScript coding. So it won't be easy :)
