Please Read/Skim:

• Automating the Design of Graphical Presentations of Relational Information by Jock Mackinlay (PDF)
  This seminal paper from 1986 shows a slightly different angle on the Marks and Channels concept, particularly the rankings. Please pay special attention to figures 14 and 15. This work eventually became Tableau.
• A Layered Grammar of Graphics
  This 2010 paper describes the underpinnings of the highly influential R package ggplot2.
• Vega-Lite: A Grammar of Interactive Graphics
  This 2017 paper describes the Vega-Lite system, which we'll be using this week in the assignment.
• Effective Chart Design
  A guide for choosing the right visualization.

If you did get a copy of "Semiology of Graphics"

• Have a look through Chapter II. "The Properties of the graphic system". I recommend speed-reading this in the first pass, spending a few seconds on each page and taking in all the graphics.
