17、to either emphasize important information or de-emphasize irrel- evant details; for example, the most important information in a subway map is the sequence of stops along each line and the transfer stops that allow

18、riders to change lines. Most sub- way passengers do not need to know the true geographic path of each line. Based on this insight, map designer Harry Beck redesigned the map of the London Underground in 1933 using t

22、he aesthetic style of the visualization. Accordingly, we use the term “design principle” as a shorthand for guidelines that help improve viewers’ comprehension of visually encoded information. Design principles are

23、usually not strict rules, but rules of thumb that might even oppose and contradict one another. For instance, Beck did not completely straighten the sub- way lines; he included a few turns in them to give viewers a

24、sense of a line’s overall spatial layout. Skilled visual designers implicitly apply the relevant design principles and balance the trade-offs between them in an itera- tive process of creating example de- signs, crit

25、iquing the examples, and improving the designs based on the critiques. Designers usually do not directly apply an explicitly defined set of design principles. The principles are a form of tacit knowledge that de- si

26、gners learn by creating and studying examples. It is far more common for books on visual design to contain vi- sual examples rather than explicit de- sign principles. Many of the analysts and end users inundated with

27、 data and charged with creating visualizations are not trained designers. Thus, our work aims to identify domain-specific design prin- ciples, instantiating them within au- tomated visualization design systems that e
