As promised, I am putting lecture slides online (in Canvas). You should be able to find them in the “files” part of Canvas, but if you need a direct link:
https://canvas.wisc.edu/courses/170656/files/folder/Slides
My experiments with lecture capture for the first day is online at: https://mediaspace.wisc.edu/media/CS765+Data+Visualization+2019+-+Lecture+1/0_8kr0glxt
In the future, I may try to put preliminary versions of the slides online before class.
