Displaying multiple levels of data visually has been proposed to
address the challenge of limited screen space. Although many
previous empirical studies have addressed different aspects of this
question, the information visualization research community does not
currently have a clearly articulated consensus on how, when, or
even if displaying data at multiple levels is effective. To shed
more light on this complex topic, we conducted a systematic review
of 22 existing multi-level interface studies to extract high-level
design guidelines. To facilitate discussion, we cast our analysis
findings into a four-point decision tree: (1) When are multi-level
displays useful? (2) What should the higher visual levels display?
(3) Should the different visual levels be displayed simultaneously,
or one at a time? (4) Should the visual levels be embedded in a
single display, or separated into multiple displays? Our analysis
resulted in three design guidelines: (1) the number of levels in
display and data should match; (2) high visual levels should only
display task-relevant information; (3) simultaneous display, rather
than temporal switching, is suitable for tasks with multi-level
answers. Table of Contents: Introduction / Terminology /

Displays? / Decision 3: Simultaneous or Temporal Displays of the
Multiple Visual Levels / Decision 4: How to Spatially Arrange the
Visual Levels, Embedded or Separate? / Limitations of Study /
