// bit-o-data: point sets for juttle demos (over in bit-o-juttle)

Bit-O-Data

Data for use in juttle examples. These are JSON arrays of points, and you get them into your juttle by sourcing their "raw" URL, eg,

source "https://gist.githubusercontent.com/welch/85872ad486a56eb9556a/raw/984b1504f7036ff548d59b2a7cb500109779869f/events.json"
