Hans Rosling as a performer.

Bubble charts are awesome, just look at Hans Rosling.  The guy literally swallows a sword on stage and you think it's the chart type that made the presentation.
I think we tend to undervalue Hans Rosling as a performer while hyping his data visualization.

When you first watched his early *TED talks did you think, “Maybe I should create a bubble chart?” Or did you think, “I wish I could captivate an audience like that?”

Originally for me it was the former and not the latter, but that’s certainly changed over the years.

*TED 2007 was his sword swallowing year.
