Day 76 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:

Reading Nathan Yau’s book Data Points – Visualization that Means Something

p. 211-242 Annotation

Three Takeaways

  • Use annotations to make statistical trends in charts clear – esp since a lot of lay audiences won’t understand something like a scatterplot or histogram offhand p. 232
  • Do the math and call out trends and important info with annotations  combined with highlighting and color hue p. 236-237
  • If using new visual encodings, prime your audience because they may not be able to understand data offhand p. 242
