Visualization shown in local notebook, not on GitHub

[johann-petrak]

I am using version 2.1.2 and code like this in my jupyter notebook:

pvis = pyLDAvis.sklearn.prepare(ldamodel, dtm, vect, R=30, mds="pcoa")
pyLDAvis.display(pvis)

This works fine in my local jupyter notebook. But when I display the same notebook in my github repo, the output does not show the visualization but just a small grey rectangle.

All the other graphics in my notebook do show fine though. Is there a way to make this work on GitHub?
