Due to the rapid development of information technology, we are confronted with an unprecedented flood of data. Information visualization deals with the graphical representation of abstract data without spatial structure. Abstract data visualization uses visual metaphors and interaction to extract information from the data. Typical application scenarios are analyzing financial transactions or social networks, geography, text analysis, or visualization of software source code. In this lecture, different techniques are presented to visualize different data types. In particular, the following topics are covered:
- Colors and Color Models
- Data Types
- Multivariate Data
- Networks (Graphs) and time dependent Networks
- Hierarchies
- Text visualization
