[whatwg] Canvas for web spectrometry

[Michael Norton]

Mention of web spectrometer working group (WSWG) below (last paragraph in thread with Kyle) if anyone is interested.

One use case would be bringing to browsers a supplement to users' History pages: a Progress page, for without one's adequate knowledge of history, how is there progress?  (May sound esoteric or existential but i am actually being very logical and enjoying it too :-)

Data.gov data)
