state of the union visualization

a visualization of all all the State of the Union addresses from 1790 to 2006, showing how specific words gain & lose prominence over time, & linking information on the historical context for their use. the graphic representation focuses on the relationship between individual addresses as compared to the entire collection of addresses, highlighting what is different about the selected document.
the vertical position of the words is determined by a statistical measure of significance (of the word in the document as compared to the word frequency in the whole corpus), the horizontal position is alphabetical, & the size is based on raw frequency in the document.
