Places I've been to by Alessandro Zotta, Politecnico di Milano
The visualization is a self-exploration study. This is how I prepared myself to travel to the multiple destinations that are mapped, according to my browser history. Each ring represents a website that I visited before going to the city, chronologically ordered from center to outside, so the more the rings, the more research I made. Colours indicate categories: did I look more for conferences lineup, accommodation, transportation or local information, such as restaurants, museums or the weather?
