The True Size of Africa

If there still had to be further proof needed that a picture may be worth more than a thousand words, here it is:

In cartography there has been a lot of attempts to educate about the true size of Africa, the Peters Projection is among the more commonly known. However that Peters map has alienated people as it is too far off of traditional viewing habits, dismisses the Mercator map for all the wrong reasons and – as this sentence shows – slips into map geekery all too easily.

So there is little left to say apart from the fact that I wish this work of statistical art a wide audience, something that has been greatly helped by Kai Krause’s decision to put in in the pblic domain. And speaking of public domain, what better way to share another related link than the View of the Earth as seen by the Apollo 17 crew traveling toward the moon.

I didn’t check the facts, it seems vaguely right to my geographical eye, but I have to admit that it floated by on the Twitter and hopefully it is more than some internet meme.

Gapminder on the Diversity of Africa

Another TED video of Hans Rosling presenting data with Gapminder. This time on The Truth About HIV, in which we learn a lot about the diversity of Africa. This is where the trendalyzer shines.

And albeit the severe topic I also wanted to bring your attention to a detail of his presentation technique. Hans Rosling uses an old-style pointer instead of the laser ones we see so very often these days and his presentation makes it very clear why that is a better choice.
