Deletion of Watergraph (2nd nomination)

Comment: The article as it is right now is completely unsourced, and in an attempt to find at least one piece of information about this term I couldn't find anything in third-party reliable sources. I found http://watergraphs.com/about/ this primary source but it doesn't even substantiate some of the claims in the article. Not to mention both of the artist mentioned as "notable" producers of this technique dont have articles here (although Summers might be notable enough for inclusion).  ,
