The visualization tool is based on the data of editors who have participated in editing Article pages in Wikiproject between August 1, 2003 and July 31, 2013. We only included editors who edited articles with the quality assessment, but we excluded editors who have never contributed articles. For example, although an editor has only contributed to Talk and User pages on any Wikiprojects, the editor is not included in our visualization.
