| |  | Chi, Huai-hsin | An Operator Interaction Framework for Visualization Systems read moreAbstract: Information visualization encounters a wide variety of different
data domains. The visualization community has developed representation
methods and interactive techniques. As a community,
we have realized that the requirements in each domain are often
dramatically different. In order to easily apply existing methods,
researchers have developed a semiology of graphic representations.
We have extended this research into a framework that includes
operators and interactions in visualization systems, such as a
visualization spreadsheet. We discuss properties of this framework
and use it to characterize operations spanning a variety of different
visualization techniques. The framework developed in this paper
enables a new way of exploring and evaluating the design space of
visualization operators, and helps end--users in their analysis tasks.
Keywords: information visualization, operators, user interactions,
view/value, framework, spreadsheet, design, extensibility,
visualization systems.
