Abstract
Visualized data and information can be inaccurate or even wrong.
Moreover, in the synthetic digital world anybody can visualize anything
in any shape or form, disregarding how users might perceive or get the
information. Worse, as technology develops, it becomes easier to do so.
Understanding the data and information and reaching sound decisions
require knowing what pieces of information or data are accurate,
complete, consistent, and certain, identifying which are not and by how
much, and making the presentation accurate. The author discusses the
following issues: sources of imperfection in information; representing
the degree of imperfection; intuitive visual metaphors and cues for
representing imperfection; imperfect presentation; and notions of
managing imperfection and visualization
