This bubble graph shows how number of participants and proportion of new account creators relate to the number of pages of text produced each edit-a-thon hour. As illustrated by bubble size and label, in which larger bubbles represent more pages of text each hour, there was a lot of variation in the number of pages of text produced per hour. The two largest bubbles demonstrate an interesting thing, that high proportions of new editors in an edit-a-thon group does not necessarily lead to less productivity, new user groups can be highly productive in terms of adding content to the article namespace.
