Document cloud comparison

The two clouds show the words related to the focus word in both documents in the same manner as for the single Word Association Cloud. The only difference is that colour is used to indicate words that are unique to one document or another. The words in blue on the left are unique to the 2007 SOTU and those in red on the right are unique to the 2008 SOTU. As before, you can click on a word to bring it in focus or click on the top edit box to change it. The clouds are linked in this case so that they always show the same word for both documents.
