Feature summary (what you would like to be able to do and where):
Allow Lua modules to fetch PageViews API data. How to do this is completely up to you.

Use case(s) (list the steps that you performed to discover that problem, and describe the actual underlying problem which you want to solve. Do not describe only a solution):
I want to rewrite the Graph:PageViews template into using the dynamic graphs mechanism (see this and this -- effectively, now we can make graphs with arbitrary data from Lua, e.g. taken from Wikidata. External Data extension would be sooo useful here).

Benefits (why should this be implemented?):
This will make Graph:PageViews template work again.
