Probably everyone has seen Hans Rosling’s famous TED talk by now. I recently came across a couple of other exceptional talks on data visualization:
Hans Rosling again: Let my dataset change your mindset. If only all statistics lecturers were this dynamic!
David McCandless: The beauty of data visualization. Not so exciting as Hans, but some great examples.
And for those in the UK, look out for “The Joy of Stats”, coming soon on BBC4.
