These are my notes on the book Envisioning Information by Edward R. Tufte.
How do we represent the world on a piece of paper? We do this so often without realizing that we do it. Every article or essay that is written is a representation of an idea or an experience that existed beyond two dimensions. Every image that is drawn to capture a moment, explain a concept, or create an emotion is a two dimensional representation for what exists in greater dimensions.
Design Excellence is the concept of effective and efficient representation of real world data in two dimensions. These priciples of desing are universal.
