Analytics/Stories/EEVS/Exec visualizes new editor metrics (final)

Story

As a decision maker (exec), I can visualize a New editor graph for one of any 882 Wikimedia projects so that I can make decisions.

New editor defined here: https://meta.wikimedia.org/wiki/Research:New_editor
Can load any of the 882 projects (http://en.wikipedia.org/w/api.php?action=sitematrix)
No UI needed to select which one of 882 projects (it's out of scope for this story). Editing URL could be sufficient for selecting the project to display.
Cron user runs wikimetrics job to produce data
all data is private
