Study Notes
Information Visualization
- Information visualization is a distinctive field of research with less than a few decades of history, but has rapidly become a far-reaching, interdisciplinary research field.
- Works on information visualization are found in various subject domains, including information retrieval, hypertext, World Wide Web, digital libraries, and human-computer interaction.
Characteristics of Information Visualization
- Visual representation is often more effective than written text in understanding complex systems, making decisions, and finding information hidden in data.
- The boundary between information visualization and related fields like scientific visualization and simulation modeling is becoming increasingly blurred.
Importance of Visual Representation
- Visual representations help us to illustrate concepts that are difficult to explain verbally.
- The use of visual representation offers a valid communication tool, but defining effective representations is a challenge.
Applications of Information Visualization
- Explorative analysis of data benefits from visual representations, enabling the identification of properties, relationships, or patterns.
- Visual representation is also used for confirmative analysis on structural relationships between series of data.
From Data to Wisdom
- Information visualization is located between data and information, providing methods and tools to organize and represent data to produce information.
- Data lacks meaning, and must be processed, organized, and presented in a suitable format to create information.
- Knowledge is created by integrating information with experiences, and wisdom is the highest level of comprehension, achieved through self-induced contemplation and interpretation of knowledge.
Mental Models
- Visualizing data is a cognitive activity where people build mental models of data, or internal representations of the world around them.
- Diagrams are more effective due to properties like locality, minimizing labeling, and perceptual enhancement.
Scientific Visualization vs. Information Visualization
- Scientific visualization deals with data that has a correspondence in physical space, aiming to visually represent scientific experiments or natural phenomena.
- Information visualization deals with visualization of abstract data that don't necessarily have a spatial dimension.
