A series of visualizations [flickr.com] that represent the top organizations and people mentioned in the news articles of the New York Times for a given year of news between 1984 and 2009. Connections between these entities are drawn, so that relationships can be found and followed. These circular graphs are based on the faceted searching abilities of the NYTimes Article Search API, that were released a short while ago.

Reminds me of the circular graph of the Eigenfactor project, although some subtle differences in "bundling" the edges for visual clarity exist.
