I conducted a session on Wed, 04 Nov 2026 at [ED5518: Data Visualization for Engineers](https://ed.iitm.ac.in/) - Department of Engineering Design, IIT Madras, Chennai.

**Speakers**: [Anand S](https://www.s-anand.net/)

**Summary**: A live-lab class on testing visualizations and phone apps: commit to an answer before discussing, check that a chart is true and that it works for its audience, use AI as a different kind of reviewer rather than a stand-in for people, and ask busy people “A or B?”
