Visual Variables & Tableau

Source for Visual Variables & Tableau Workshop presentations/information


Data visualization is an important tool for researchers, assisting in both analysis and communication of results. The use of appropriate visualization techniques can greatly increase the ability to gain insight from and ease the communication of data.

Creation of effective visual representations relies highly on the use of what are known as visual variables. Visual variables include colour, brightness, position, orientation, shade, and texture. Appropriate use of these properties is a key component of mapping raw data to a visual representation. Through effective use of visual variables a great number of properties can be embedded in a single visualization.
