Great piece of work

I just have to recommend that you go to the interactive chart at this site, which allows you track, over time, for the various nations of the world, movements in factors such as the per-capita income and the average life expectancy at birth. It’s an incredibly powerful and interactive tool.
You can simply select a country, or a number of countries, from the list on the right hand side, and press “play”; however for a demonstration of the full power of the site, I recommend you click on “How to use” for a 2-minute demo.
