Link roundup for August 2022

There’s a lot of device on making graphs, but sometimes research on whether the advice works is harder to come by.

This research paper on graph design tries to assess whether “decluttering” (Edward Tufte’s “data to ink ratio”) and “focus,” which is annotation of graphs. I have to say “try” because the sample size for the experiment is just 24 people, which seems small for a topic like this.

Dot plot showing ratings for the three visualization design on a scale from 1 to 5 on aesthetics, clarity, professionalism, and trustworthiness. Focused graphics rates highest in all four categories.

“Focusing” on a graph was very effective in helping people remember. 

Removing clutter had a smaller effect, but people generally liked those graphs a little better.

People like to attack graphs with a lot of noise in this. Stuart Ritchie reminds us, “Noise is why we use statistics

 And that’s it for this month!
