I’m doing some form of data visualization learning for 180 days straight because I need to #JFDI.  See post explaining how and why I’m doing this.

Decomposition of a Visualization:

Worldwide Oil Usage

  • What are the:
    • Variables (Data points, where they are, and how they’re represented):
      • Production y-axis, Consumption x-axis,
    • Data Types (Quantitative, Qualitative, Categorical, Continuous, etc.):
      • Quantitative, Qualitative
    • Encodings (Shape, Color, Position, etc.):
      • Size bar and bubble, Color Hue, Position on map
  • What works well here?
    • Using a single color to call out and lines for averages
  • What does not work well and what would I improve?
    • Could have used a less biased source than BP perhaps?
  • What is the data source?  Do I see any problems with how it’s cited/used?
    • BP Review
  • Any other comments about what I learned?
    • Great use to multiple visuals and highlighting tool tips
