/* EverybodyLikesPie(charts..)
Creates a pie chart of the size of current default gadgets to help find low-hanging fruit
This script is public domain, irrevocably released as WTFPL Version 2[www.wtfpl.net/about/] by its author, Alexis Jazz.
As of 2023-09-12, this script isn't thoroughly tested or polished and it's mostly a proof of concept. Maybe you find its output helpful, maybe you won't.
Todo:
* get {{pie chart}} template name from Wikidata Q6121704
* make second chart of all gadgets (not just the default ones)
* provide the absolute sizes
* provide gzipped sizes
* make loop to cover multiple projects at once
* some sort of interface
* sort by size
* boo synchronous http requests boo
* many other things I guess
