Day 135 of 180 Days of Data Viz Learning #jfdi

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:

The Functional Art: An Introduction to Information Graphics and Visualization by Alberto Cairo

p 123-147 Visualizing for the Mind

Three Takeaways

  • Slopegraphs are great for comparing values and show correlation, eg percentage of a state with ba and higher and percentage of obese people in a state p 127
  • Example of too much going on for high-level visual perception, photographs versus diagrams of how to open an emergency exit on a plane.  Sometimes “what is needed here is not realism” p 135
  • “The better we understand the shortcuts the mind uses to make sense of the world, the better we will be able to anticipate them and to take advantage of them for our purposes  As Robert Spence has pointed out (2007) visualization is not something that happens on a page or on a screen; it happens in the mind/  The presentation on the page or screen is merely an aid to facilitate that insight” p 147
