failing to render after vega3-extension install

[smoh]

I'm failing to render vega-lite charts in jupyterlab after vega3-extension is installed.

jupyterlab                0.31.8                   py36_1    conda-forge
---
$ jupyter labextension list
JupyterLab v0.31.8
Known labextensions:
   app dir: /Users/semyeong/anaconda2/envs/research/share/jupyter/lab
@jupyterlab/vega3-extension
        @jupyterlab/vega3-extension v0.14.2  enabled  OK

Trying to use altair, I get

JavaScript output is disabled in JupyterLab

I also tried copy-paste the example in vega3-extension README, and get empty output.
Can anyone help me getting this to work?

The following packages will be UPDATED:

Proceed ([y]/n)? y

jupyter-1.0.0- 100% |######################################################################| Time: 0:00:00   6.09 MB/s

In my browser console, I have

The same code works with just jupyter notebook or if I go to /notebooks/path/to/notebook and try executing there..

This extension only works in jupyter lab. You need https://github.com/vega/ipyvega for Jupyter notebooks.
