Day 101 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 Visualize This

238-258 Spotting Differences

Three Takeaways:

  • Star charts, with several axis and min value and max value as end of stars, can be good for multivariate data, especially with several side-by-side with color fills p. 244
    • eg different measures of crime per state
  • Use parallel coordinates/connecting lines to look for trends across multiple units.  Multiple axes next to each other with lines representing min and max p 251
    • eg different education measures, test scores, gpa, etc.
  • Make use of multi-dimensional scaling to reduce to find groups within data set or population p 258
