Information visualization theory and the grammar of graphics for modern data analysis

For the second in the 'teach me something' series, Roger Beecham gave an overview of key theory and principles in Information Visualization design (talk slides). As well as demonstrating how this theory supports modern data analysis workflows, he argued that awareness of this theory is necessary for understanding well-known, and/or newly important, toolkits for data visualization -- Tableau, ggplot2 and Vega-Lite (newly important).

Some recent teaching materials on which this session was based can be accessed from:

• ggplot2 for data analysis: session 1 notes, session 2 notes
• Vega-Lite for (web-based) data vis: session notes
