Day 70 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.

Learning at JFK!  Air France Lounge!  Where luxury goes to die!

Decomposition of a Visualization:

Bernie Sanders’s vast universe of donors, mapped

  • What are the:
    • Variables (Data points, where they are, and how they’re represented):
      • Donations by size of circle, map geo by zip, size on pie chart
    • Data Types (Quantitative, Qualitative, Categorical, Continuous, etc.):
      • Quantitative
    • Encodings (Shape, Color, Position, etc.):
      • Color hue, position, size
  • What works well here?
    • Animation and showing difference
  • What does not work well and what would I improve?
    • Last pie chart should have been colored with same color hue used for map chart about Bernie Sanders for continuity of narrative.
  • What is the data source?  Do I see any problems with how it’s cited/used?
    • FEC Reports
  • Any other comments about what I learned?
    • Wildly good example of animation and pie charts, frequently abused visualization elements
