The Editing and Deletion procedures at Wikipedia get a lot of attention these days, and a new visualization called ‘Notabilia’ shines a light specifically on the latter.  Mapping the choices between ‘keep’ and ‘delete’ amongst the editors, it creates an interesting tree-style visualization.

The online visualization visualizes 100 Article for Deletion (AfD) discussions that took the longest amount of time. A discussion is represented by a thread starting at the bottom center. Each time a user joins an AfD discussion and recommends to ‘keep’, ‘merge’, or ‘redirect’ the article a green segment leaning towards the left is added. Each time a user recommends to ‘delete’ the article a red segment leaning towards the right is added. As the discussion progresses, the length of the segments as well as the angle slowly decay.
