As far as data visualization is concerned, especially dashboards in which each widget answers a specific question and gives a limited amount of information, we hope to explain complex phenomena with generic questions and formatted answers.
Most of the time, data is just what we take from the world to answer our most valuable questions. We lose the sense of what data represents. Thus, its complexity in not considered.Read more...
