The World We Live In #1: Obesity And Cells

Lesson learned, and the wheels keep turning (The Killers – The world we live in)

I discovered this site with a huge amount of data waiting to be analyzed. The first thing I’ve done is this simple graph, where you can see relationship between cellular subscribers and obese people. Bubbles are countries and its size depends on the population:
TWWLI1
Some quick conclusions:

  • The more cellular subscribers, the more obese people
  • Pacific islands such as Kiribati, Palau and Tonga are plenty of happy people
  • Singapore people are thinner than they should be
  • How do Saudi Arabian and Panamanian manage two cellulars?

This is the world we live in.

    1. Such a discovery googleVis package! I will use for sure, beginning for solving a problem I have actually in my work! Thanks a lot đŸ™‚
