No display in jupyter notebook

[soerenwolfers]

Someone else posted this before but in a hijacking attempt of another issue, so let me repeat it here:

pivot_ui(df) does not display anything for some users (including me).

See from the other issue as well as yet another issue, which I think describes the same problem but isn't very specific about it.

In my case, the issue was that the notebook didn't have internet access, which is required by the js part of pivottablejs. Opening this issue for documentation, but also because I think there would be a serious benefit to get this work offline.
