It’s hard to imagine a career, which completely doesn’t need making some data understandable. In the world where information is everywhere, it is necessary to represent it properly, if we want to be heard and understood. That’s why the talk about data visualization given by Bartosz Borucki from the ICM UW, was indeed useful and interesting.
