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.
