This is a project by @emilyinamillion that utilizes topic modeling with Non Negative Matrix factorization (python) and has an accompanying D3.js visualization. Read the blog post here!
If you came here for the topic modeling, one of my ipython notebooks walks through the other algorithms I tried as well as my reasoning for why I settled on NMF.
If you came here for the D3.js, the visualization folder is the entire contents of the live D3.js visualization currently available on Bl.ocks. The visualization lives here.
