  32. A word on pie charts...

  33. Bad Pie Charts - Too many values - Differences hard to understand - Distribution? - (Confusing colors)

  34. Bad Pie Charts - Too many values - Not adding up to 100% - Differences hard to understand - Distribution? - (Confusing colors)

  44. Line Charts vs. Bar Charts

  45. Line Charts vs. Bar Charts? Continuous values Discrete values https://online-behavior.com/analytics/data-visualization

  46. Wrap up - Choose appropriate bin-sizes - violin plots for compare distributions - Label error bars - Don't confound box plots and error bars - Avoid pie charts - Line charts for continuous data

  47. Further Readings Fundamentals of data visualization: a primer on making informative and compelling figures Hypothetical outcome plots outperform error bars and violin plots for inferences about reliability of variable ordering Arcs, angles, or areas: Individual data encodings in pie and donut charts The truthful art: data, charts, and maps for communication
