I found the chapter on pages 52-65 to be insignful and filled with variable information. What this chapter deals with is the technique of layering and separation of information and data in design. The point of this chapter, according to Tufte, is to find strategies that show details adn complexity. The failure to do so reflect badly on the design. However, Tufte points out that effective ways of layering and separation is no easy task. Many issues can come up. There is an example.
Tufte explains tha several elements that go together an flatland tend to interact, which creates non-information patterns and textures through their combined presense. Tufte cites Josef Albers on pages 53 who says that this is an effect know as 1+1=3 or more, when 2 elements show themselves along with assorted incidental by-products of their partnership. While it has a nice effect, it reveals itself to be a danger to data display because it can become obstrusive.
What I got from reading this chapter is that information is made up of "differences that make a difference" (65). It means using effective stragtegies to showcase meaning in your designcan help make the distinction look presentable. By not following that, it will look cluttered and featured incoherent displays with misinformation.
