Bill Gates wrote to me to inform how the world has changed since '89. To be honest he just tweeted :) so no reason to keep this confidential: Gates annual letter.
The most interesting to me was the chart showing change in percentage of people living on less than $1.25 per day, so I decided to create my version, check both.
The chart was taken from this youtube film.
... and my version of this chart; done out of bread, cheese and red pepper.
It was a lot of hard work and pain in neck :( no more working with data in this way, now 'don't play with your food' has a different meaning to me. Ok there is just one adventage of this method, you can work and snack.
