Overall aims and purpose
Information Visualization (IV) focuses on the use of visualization techniques to help users understand and analyze non-scientific and abstract data. Such abstract data includes numerical data in tabular form, textual information and associative (network) sources, and contain multiple variables. The aim of this course is to introduce principles of information visualization, develop IV critiquing skills, learn about different Information Visualization designs, and gain foundational skills to design new innovative Information Visualisations through planning by sketching and implementation of those designs.
- The history and future of Information Visualization; the challenges of Information Visualization; tasks; user, perception, data types.
- Looking at data. Data capture and problems of capturing data. Selection/abstraction of data (aggregation, sampling; binning; cropping); Big data challenges.
- Perception and interpretation; Encoding of value; Encoding of relation; Models: Bertin, Mackinlay (Quantitative, Ordinal, and Categorical), Semiotics.
- Design of new visualisations, and considering alternative solutions (using sketching and the Five Design Sheets as a planning method) and critical analysis of these visualisations.
- Current visualisation designs, including traditional plots (bar, line, scatter etc.), parallel coordinate plots, treemaps, re-orderable matrix; scatter plot matrix.
- Interaction and exploration, looking at focus + context and distortion technique; multiple views and composite interaction; brushing; animation.
