I have passed along your feedback/inquiry on the Wikia Visualization to that project's manager.

As for your question about MediaWiki 1.19, that is something we anticipate happening rather soon. We were hoping to have already done that by now, but personnel wise we haven't had the availability needed to go ahead and make that switch quite yet.
