ABSTRACT
Visual analytics is a science that involves the integration of interactive visual interfaces with
analytical techniques to develop systems that facilitate reasoning over, and interpretation of, com-
plex data. As the volume of health-related information continues to increase at unprecedented rates,
there is a critical need to study effective ways to support the analysis of large amounts of data by
leveraging human-computer interaction and graphical interfaces. This need is particularly evident
in healthcare organizations where information overload could result in different diagnoses and in-
terpretations.
