Im assuming if one wanted to d3.nest the query results you could simply put d3 package in the same dir and use require('d3')??

I'd probably use GROUP BY and do that on the SQL side. But conceivably you could use D3 to do that as well. I'm not sure if D3 is packaged up correctly to work as require("d3"), but in theory that could be made to work.

Yea.. I would normally do it SQL side, but in this particular circumstance performance favors transformations in the middleware and not in DB. Ill give it a go. Thx!
