Notabilia visualizes Article for Deletion (AfD) discussions in the English Wikipedia. AfD discussions are 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.
