title: Export pyLDAvis graphs as standalone webpage
body: <p>i am analysing text with topic modelling and using Gensim and pyLDAvis for that. Would like to share the results with distant colleagues, without a need for them to install python and all required libraries. 
  Is there a way to export interactive graphs as HTML/JS files that could be uploaded to any web server?
  I've found something mentioned in documentation, but have no idea how to implement it:
