Interactive Data Visualization

Objectives

Knowledge

  • What is Information Visualization, Data Visualization (DV) and the different purposes of DV.
  • The role of interactivity in DV and the general interaction patterns.
  • The concept of Visual Variable and the practical consequence in the design of Interactive Data Visualization (IDV).
  • The classification of data for DV purposes and the impact on IDV.
  • For each type of data the most relevant available techniques.
  • Due to its wide applicability, some deep understanding on Visualization Techniques for multivariate Data time oriented data and Geospatial Data.
  • The main components of general IDV systems and the principal characteristics required on modern IDV systems.
  • The available approaches to Compare and Evaluate Visualization Techniques and Systems.
  • The actual trends in IDV and their role in more general systems and applications.

Application

  • Choose the visual variables and visualization techniques for a given data set and purposes.
  • Use a given an existing IDV system to explore one or more data sets.
  • Based on existing frameworks and platforms, design and build an IDV system appropriate for a class of data sets and a class of exploration and visualization tasks.
  • Setup an experimental environment to evaluate a DV technique. Analyze the data gathered in the experimentation.

Soft-Skills

  • Understand the multidisciplinary nature of the area and the relationship with other areas.
  • Explore the experimental nature for design IDV systems.

Additional readings will be provided during classes and through the course website (including lecture slides).

Teaching method

In the lectures the course content is presented, illustrated with application examples and references to related work. The laboratory classes are intended for specification, development and presentation of the project that deals with topics presented during the lectures.

The evaluation of the course consists of five elements: two mid-term written individual tests and one project, with several phases (specification, state of the art and code/interface) that together account for a project to develop a interactive data visualization application, using real data.

Evaluation method

The evaluation of the course consists of five elements: two mid-term written individual tests and one project, with several phases (specification, state of the art and code/interface) that together account for a project to develop a interactive data visualization application, using real data..

Final grade formula:
Final_Grade = 25%Test1 + 25%Test2 + 10%Specification + 15%Paper + 25%Códe&Interface

Course approval requires the following minimal grades:

(mean (Test1; Test2) >= 10) AND
(mean(Specification; Paper;Code&Interface) >= 10) AND
(Test1 >= 8) AND
(Test2 >= 8)

Students approved in the project and not approved in the tests may also do a final exam, and the resulting grade replaces the grades of the tests in the final grade formula.
