Icaro Doria, a Brazilian man, working for a magazine in Portugal started this campaign using real data from the UN and flag images, he’s created whats known as Meet the World. The colors within the flags from its respective country are used to represent current, geographical relevant issues. Take a look.
Interesting infographic-y type of things. Here, the designer barely had to do anything at all. The flag’s design already provided him/her with the graph they needed. Sometimes, the design you need/want is already right in front of you.
