What you'll learn

  • Learn a hierarchy of graphical encodings of information from easiest to decode to most difficult and how to apply this hierarchy when making graphical displays
  • Gain a basic understanding of gestalt psychology and its implications for data visualization
  • Discover other useful ideas including Weber's law and Cleveland's rule of banking to 45


John Rauser explains a few of the most important results from research into the functioning of the human visual system and the question of how humans decode information presented in graphical form. By understanding and applying this research when designing statistical graphics, you can simplify difficult analytical tasks as much as possible.
