I conducted a session on Wed, 07 Oct 2026 at [ED5518: Data Visualization for Engineers](https://ed.iitm.ac.in/) - Department of Engineering Design, IIT Madras, Chennai (remote).

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

**Summary**: AI makes pictures cheap to create but harder to trust: the reader may be another AI, and a chart, map or CAD model that looks right still needs an independent check.

**Takeaways**:

1. Doing is easy. Choosing what and how isn't.
2. Design for humans _and_ agents.
3. Keep asking "How can I use this?" - that's how you learn.
4. Write the objectives before you start. That's how you know if agents did it right.
