An animated graphic is a graphic that moves, often in a GIF or movie format. It can be really useful to describe the evolution of something, or to denote the difference between two states (going from one to another and


backward). The most famous example is probably the TED talk of Hans Rosling about the ‘developing world’. Technically speaking, the trick is to build a lot of charts (usually through a loop) and compile them  into a single


animation using Image Magick. Download it here, and see examples for instructions on how to make the animation.
