I’m doing some form of data visualization learning for 180 days because I need to #JFDI.

See post explaining how and why I’m doing this.

Reading and Learning Data Visualization Theoretically/Critically:

Show Me the Numbers by Stephen Few

Three Takeaways Today

Chapter 5 Visual Perception and Graphical Communication
  • “Built into visual perception is the assumption that the light is coming from above.”  Our real-life perception of everyday objects influence how we interpret graphics, in this case how shapes are “lit” p 62
  • There is iconic memory that relates to pre attentive processing in visuals, the fast recognition of color hues in text.  It is important to think of iconic memory when quickly making groups distinctive and highlighting objects p 66
  • Working memory is temporary and has limited storage capacity, only three or four chunks can be stored at one time.  Think of how you structure tables and graphs – if you have ten different symbols, the reader won’t be able to process it p 67
