Hans Rosling’s TED presentation on international economic development issues. Pure genius of information visualisation, transforming time-series changes into a kind of sportscasting.

This is a classic. Most vis classes use this as an example. I was planning on making people watch it later in the semester. I re-watched it and it reminded me how good it is.
But pay attention: what makes it good is not the graphs themselves (they’re good, but not that unusual), but how good Rosling is at “integrating” it into his discussion.
