For the curious, here's a port of the Dbmonster demo to a simple Underscore template — the kind of base-level rendering strategy you might start with in a Backbone app. (And vintage 2009 technology.)

Edit:

To head off grumbling at the pass — It would also be easy to do a slightly less-simple version that keeps the flickering impossible-to-read popups open (putting redundant tooltip DOM into each table cell isn't how you'd actually write this), and the server names selectable ... but those particular "features" don't really seem relevant to this particular UI.
