I've been searching for something like that for a while now. A metrics web framework that consumes and renders json/edn would be interesting.

I've been using shopify/dashing for metrics display:

You can post JSON directly to each widget. It's also based on Sinatra.

Someone already created a widget for Rickshaw graphs, I suppose it could be adapted to use D3.js.
