This chapter is mostly about comparing data points. Some of the tasksyou can do when comparing data points are ordering, sorting, and ranking. Comparisons are found everywhere in data visualization, so much so that Edward Tufte says that “compared with what?” is “the deep, fundamental question in statistical analysis.” In a more or less explicit way, you’ll find comparisons at the heart of every category in our chart classification. If you aren’t comparing data points, you’re comparing trends or profiles.
