Study Notes
What is Data Visualization?
- Data visualization is the process of converting raw data into easily understood pictures of information that enable fast and effective decisions.
- It is used in software applications to provide an intuitive graphical interface.
- It is applied to many areas, including military, private business sectors, and scientific research.
Types of Data Visualization
- Scientific visualization: specifically concerned with data that has a well-defined representation in 2D or 3D space (e.g., from simulation mesh or scanner).
- Information visualization: concerned with data that does not have a well-defined representation in 2D or 3D space (i.e., “abstract data”).
Importance of Data Visualization
- Data visualization conveys complex results as understandable images.
- Data visualization is emerging as an important fusion of graphics, scientific visualization, databases, and human-computer interaction.
Why Do We Visualize Data?
- Making data engaging and easily digestible.
- Identifying relationships, trends, and outliers within a set of data.
- Telling a story found within the data.
- Reinforcing an argument or opinion.
- Highlighting the important parts of a set of data.
- Thinking is slow, but seeing is fast.
How Do We Visualize Data?
- Pre-attentive attributes: things that our brain processes in milliseconds, before we pay attention to everything else.
- Types of pre-attentive attributes: length, width, orientation, size, shape, enclosure, 2D position, grouping, color (hue), and color (intensity).
- Color in data visualizations: used to distinguish groups of data, represent data values, and highlight.
Benefits of Data Visualization
- Allows users to see several different perspectives of the data.
- Makes it possible to interpret vast amounts of data.
- Offers the ability to note exceptions in the data.
- Allows the user to analyze visual patterns in the data.
- Enables users to explore trends within a database through visualization.
- Helps translate data patterns into insights, making it a highly effective decision-making tool.
- Equips users with the ability to see influences that would otherwise be difficult to find.
- Reduces the time and difficulty it takes to move from data to decision making.
