Nutella Unica is a project in which Ferrero created 7 million unique patterned jars of Nutella. Apparently, they used an algorithm to do this, and each jar had a unique code. The project was implemented in Italy and sold out in a month. They are applying it in other countries as well. This is a good example of commercial visualization.
