In a talk by Marc Faber that I attended recently, he showed how quickly the developing world has advanced economically, and he argued that it should not be ignored by investors.
In this entertaining talk Hans Rosling, a Swedish doctor and statistician, illustrates how many developing countries have also advanced rapidly in terms of health and education.
Rosling uses an amazing graphics system that he and his team developed. The data is presented in at least five dimensions: x and y axes, time, marker size, and color (which you might consider to be three dimensions). Rosling’s energetic commentary adds to the richness of the presentation.
