Features
Multi-dimensional data is usually published as a series of tables and ranked lists, or
made accessible through a standard database interface, where queries can be issued by filling in fields in
forms. The fact that data is accessible though does not automatically mean that it is also useable.
SurveyVisualizer is an alternative way of publishing such data. It is a highly interactive
visualization tool with the following key characteristics:
-
Provide overview of the global relationships between objects: Multiple views show the different
aspects of the data at the same time.
- Encourage and support exploration, discovery of unexpected structures and formulation of new
hypotheses: All the views are highly interactive. They
are tightly linked so that interactions in one view are always reflected in all the others.
- Embed fine grain tasks in a global frame of reference: Specific numeric values of
attributes can be obtained by probing
the objects in the views, dynamic
queries on a combination of attributes can be executed by using range sliders. All actions are
supported by visual feedback, embedded in a common frame of reference.
- Take advantage of the human perceptual abilities: The visual representations make
it easy to spot outliers, patterns or anomalies. High interactivity and immediate feedback support
our fluid and informal way of problem solving. The tool fits the way we naturally think and work.
