This is a great little clip. I've been recently becoming more and more fascinated by data, both the insights it can give us and how it can be used predictively. This video gives a decent insight into how the relationship between wealth and health has changed around the world, but the main reason it's impressive is in showing the sheer power of visualisation in conveying information.

Just imagine if more educators were easily able to bring data to life in this way, and present insights so vividly and interactively. The classroom could get a whole lot more exciting!
