Notes:

• My time was booked more-or-less constantly from 4:00 yesterday to 10:00 p.m. yesterday, and from 8:00 a.m. today until class time today. In between, I had family responsibilities. I've done my best to answer questions that came in last night, but I haven't gotten to all of them. 2:15 today is my next free time.
• I'll answer more questions in class today.

Overview:

• Short introduction to data visualization.
• Lab.

## Background

• Goal: Visualize multivariate information.
• Strategy: Convert attributes (variables) to different aspects of things (e.g., simple shapes) on the screen.
• Some attributes are represented positionally.
• Some attributes are represented in other ways (shape, color, size, shade).

## Lab

• We'll explore most of these issues in the lab.
• We'll continue this work tomorrow and Friday.
