ABSTRACT
This chapter explains choices about how to facet data across multiple views. One option for showing views is juxtapose them side by side, leading to many choices of how to coordinate these views with each other. The other option is to superimpose the views as layers on top of each other. When the views show different data, a set of choices covers how to partition data across multiple views. The main design choices for juxtaposed views cover how to coordinate them: which visual encoding channels are shared between them, how much of the data is shared between them, and whether the navigation is synchronized. The verb facet means to split; this chapter covers the design choices that pertain to splitting up the display, into either multiple views or layers. One of the five major approaches to handling visual complexity involves faceting information: juxtaposing coordinated views side by side and superimposing layers within a single view.
