Isabel Meirelles gave a presentation at Sheridan College’s lecture hall about why we need information visualizations. She is an information designer, author and associate professor of graphic design at Northeastern University in Boston. Her presentation looked at information visualization from a research and historical perspective. She gave us an overview of how information visualization was used in earlier centuries by scribes, doctors and more to convey complex information in a simpler form. What I found most interesting was how web design and interaction design play a huge role in making information visualizations more compelling and easier to understand.
