Streaming - no output in iPython notebook

[loredanacirstea]

Streaming visualization works in the local server. However, in there is no graphical output in the notebook. It just says:

Lightning initialized
Connected to server at http://localhost:3000

I tested other static graphs and they were shown in the output (no issue).

This is the code I was trying out: https://github.com/loredanacirstea/ipython-lightning-test
Python 3.5.2 :: Anaconda 4.2.0 (x86_64)

I also have the same problem outputs render like blank line, but the output code is actually there looking at the dev console

Using:
Jupyterlab 1.2.7
Chrome
Lightnings server from docker latest
