Flare tool: Data Visualization for Web
Slate's "News Dots" presents a constantly updated view of the day's news events as a network.
News stories are parsed for keywords which are in turn used to build up an interactive map of how often and how many keywords appear in each story. Each news story connects and weights keyword appearance (frequency).
