Overview
• What is interactivity, exactly?
• What are the three levels and features of
interactivity support in data visualization?
• Applying visual information seeking mantra
in interactive visualizations and dashboards
A key feature of data visualization is the
interactive exploration and analysis of
data and visualizations.
Interactivity (in Data Visualization)
•
Interactivity is the functionality provided by the (visualization)
system/application to let users interact with the visualization or
the system/application through a user interface.
• So, the visualization itself becomes dynamic based on user
actions, providing different views of data.
• The overall analytical or reporting application can also become
interactive and support more user needs.

Interactivity in the Visual Exploration and
Analytics Process
•
Interaction is a general feature in computing systems and
applications. It is a process that users and systems can
“work together”.
•
Interactivity is an important aspect of data exploration
and analysis, as both are interactive processes.
– Interactivity can also support other analytics tasks like data
preparation, data cleanse, model training, etc.
• Visual interactivity focuses on the interactions in various
forms of data visualizations (charts, maps, dashboards,
etc.)
•
Interactivity is essential in visual analytics where
discoveries are driven by intensive interactions with
visualizations.
Why Interactive?
• Enable multiple perspectives
–
“Static visuals can offer only pre-composed “views” of data, so multiple static views are needed to
present a variety of perspectives on the same information. A fixed image is ideal when alternate views
are neither needed nor desired, and required when publishing to a static medium, su
