After brief introductions, Steve discussed color and the use of BANs. Steve discussed “Lonely Numbers” as discussed in the new book, Factfulness: Ten Reasons We're Wrong About the World--and Why Things Are Better Than You Think by Hans Rosling.

He enjoyed the book so much, he’s read it twice!

Steve also added BANs to the Churn dashboard from Chapter 24. This updated dashboard is available for download here.

Jeff discussed some examples of “Comparing Individual Performance with Peers” from Chapter 3 of The Big Book of Dashboards. This dashboard is also available for download here.

Steve discussed “visualization we shouldn’t like, but do” and showed Jeff’s Name Dropping visualization and his redesign with the “fun removed”.

Steve also showed a beautifully-designed health care visualization by Katie McCurdy from Pictal Health.

Jeff closed the webinar with a discussion about “The Screaming Cat” and discussed various blog posts related to radar charts, dual-metric donut charts, and the various responses from within the data visualization community.

Jeff discussed how these tutorials can be useful in real-world cases, even though they may not be best practices in other cases.

The highlight of this section was Jeff telling the story of the famous Florence Nightingale Rose Chart, how it was tremendously effective in delivering a very important message at the time. Jeff also took on the daunting task of redesigning this very famous visualization.

Note from Steve: Jeff’s redesign is terrific.
