What ideas have been tried or suggested in using visualization as an aid in Wikipedia? For example, could the articles of a category be summarized as an image that would provide new insights to the user, either encyclopedia reader or writer?
When scanned books are proofread in Project Runeberg (runeberg.org, a website similar to Wikisource), a horizontal bar graph is used to indicate which pages have been proofread or not, with one pixel for each page of the book (so 500 pixels wide for a 500 page book), with green pixels for proofread pages and red pixels for not yet proofread pages. Here is an example of a partially proofread 2 volume work, at the bottom, http://runeberg.org/bokogbib/
Could something similar be useful in Wikipedia? Perhaps for overview of maintenance categories? Are there any tools at the toolserver that do such things? Has that been tried?
The various (humorous) Size-of-Wikipedia pictures come to mind, http://commons.wikimedia.org/wiki/File:Size_of_English_Wikipedia_broken_down... http://commons.wikimedia.org/wiki/File:Size_of_Wikipedia_broken_down.svg
