Just for fun I've created a visualization of articles submitted to Reddit. It presents a dynamic graph starting from the 'hottest' stories of the moment and lets you build up a more complex structure by adding related stories.
Rectangles represent articles and each one has a circle connected to it that shows the user name of the person who submitted it. You can add new articles to the graph related to an existing one by hovering over it and clicking when it is expanded. You can also add more submitted by a given user by clicking on user nodes. A right-click (or space bar) on an expanded article will open that document in a new browser window. Dark red stories have a high Reddit score and white stories a low score.
