Hans Rosling explains facts about the HIV spread around the world that will hopefully clear some of the common misunderstandings of the disease. This TED talk is not only hugely informative but also stunning to watch because of Rosling’s fantastic data visualisations.
Infographics are probably the only medium of getting eye candy and information at the same time. You can find 50 great examples collected by Francesco Mugnai in this recent blog post. If you want to continue enjoying the fun of infographics there is also what started me on infographics in the first place, a blog written by Randy Krum called Cool Infographics that delivers nice pieces from time to time. Ning even has its own Visual Thinking Map networks that serves as a collective pool for inforgraphics. Rock on.
When you see an airplane, don’t you ever wonder where it’s going, who’s on it and why they’re going where they’re going? I’ve always wondered these things when I’d see airplanes; there are so many stories happening on those flights, people meeting on board, going to see their loved ones or simply taking in another long day of work. My first place to live in London was in Mile End, an area located on the routes of most flights heading down to the City Airport in London and boy did I see and hear lots of airplanes. Sometimes I’d try to figure out the direction of the flight (provided it wasn’t circling) to make up a destination and a story to go with it; call it a mini-hobby of my student days.
I’ve also always liked the back-pages of the in-flight airline magazines that show you the lines of all the routes they cover on a map. Well, today I stumbled upon something even better – a 24hr visualisation of airplanes zipping around the globe. Enjoy.
To create this chart I turned to the CIA Factbook, where I looked up the populations of various nations and then divided this number into their land area (excluding lakes and rivers) to get the number of square feet available per person. I represented the results in squares that are all drawn to the same scale.
Today another great infographic! Justin Wehr just posted this on his blog Wehr in the World. The graphs are a compilation of comScore data from the 15 countries most populated with Internet users. According to comScore, the number of unique users worldwide has just reached a billion, which still leaves the world with only between 15 and 22 percent of its population on the Internet.
Using the comScore numbers, here is the breakdown by country and region (in unique visitors as of December, 2008; some of the numbers are rounded):
Top 15 countries, by Internet population:
- China: 179.7 million
- United States: 163.3 million
- Japan: 60.0 million
- Germany: 37.0 million
- United Kingdom: 36.7 million
- France: 34.0 million
- India: 32.1 million
- Russia: 29.0 million
- Brazil: 27.7 million
- South Korea: 27.3 million
- Canada: 21.8 million
- Italy: 20.8 million
- Spain: 17.9 million
- Mexico: 12.5 million
- Netherlands: 11.8 million
Worldwide Internet Audience
- Asia Pacific: 416 million (41.3%)
- Europe: 283 million (28.0%)
- North America: 185 million (18.4%)
- Latin America: 75 million (7.4%)
- Middle East & Africa: 49 million (4.8%)
Ok, yes, this is nerdy, but I can’t help but think this is one of the best infographics I’ve seen on evolution. I think besides those who pursue research and progress in natural sciences, those who make it approachable for laymen deserve just as much if not more applause. The sphere above is a family tree representing the evolution of mammals across 166 mln years. The timeline runs from the centre of the sphere outwards so you can track how and where the various groups split and changed. The family tree was creater by Robin Beck, a Mammalian Systematist as the University of NSW. The intricacy of the tree is quite amazing to the point of it being a little difficult to analyse, but for those interested enough, I’m sure it’ll be a joy anyway. The complete image is available as a free PDF download and to get an even better feel of it, you should watch a video by Dr. Paul Willis from ABC TV in Australia.
Now the thing to find out is whether there are such graphs available for other groups of animals and how long it might be before there is one encompassing all species! I think it would be great if someone could put this graph into a more interactive piece of software so as to make it more fun for those who might actually be able to use it in biology classes for their students.
