On "Geek" vs. "Nerd" by Burr Settles

This plot empirically teases out subtle differences between the words "geek" and "nerd". Two axes represent the words in different dimensions, and plot other English words according to their correlation with "geek" and/or "nerd" in a corpus of more than 2.6 million tweets.
Rather than plotting on a continuum from one extreme to the other, I opted for a 2D design to illustrate the extreme properties (e.g., "geek" words are more trendy or collection-oriented, whereas "nerd" words are more academic) in the top-left and bottom-right corners, as well what the two personality types share in common, which show up in varying degrees along the diagonal.
