Day 139 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.

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

p 175-190 Creating Information Graphics

Three Takeaways

  • “The more visible the functionality of an object, the easier it will be for users to create a mental model of what they can obtain from it.  Norman encourages designers to take advantage of ‘natural mappings’ or physical analogies to the real world.  If something is important in your graphic, highlight it in such a way that readers can sense its relevance and how it operates.  For instance, if you are designing buttons, make them mimic physical buttons.” eg buttons with arrows. p 189
  • “The shape of an object must visually suggest what it ‘affords.’…  If you want readers to press, pull, push, or spin virtual objects on a computer screen, design those objects so as to suggest that they are pressable, pullable, pushable, and spinnable.” p 189
  • “If a piece of information is indispensable to understand the whole story, it should always be visible,” that is not buried under a rollover or something you need to click on.” p 190
