The result was no consensus. This was a close debate. With two of the keep !voters acknowledging the sourcing is borderline there doesn't seem to be a level of consensus that would warrant a straight "keep" decision, but neither is there a consensus to merge or delete. I recommend that participants go ahead with the suggested merge from Protovis to D3.js (and also, unrelated to this close, I noticed a duplicate article at D3js that needs merging and/or redirecting). Feel free to renominate for deletion after three months or so. — Mr. Stradivarius (have a chat) 13:28, 27 August 2012 (UTC)[reply]
I don't see any indication of notability here. The two sources are the javascript library's own website and the Wikipedia article on Datavisualization. I couldn't find any references to it on Google. Seems like an insignificant script with no widespread usage. —JmaJeremy✆✎ 21:03, 11 August 2012 (UTC)[reply]
