Weekly Data Viz Decomp: The Guardian’s Premier League Transfer Window Summer 2016

Weekly data visualization decomps to keep a look out for technique and learning.

This week’s viz: Premier League: transfer window summer 2016 – interactive

Decomposition of a Visualization:

  • What are the:
    • Variables (Data points, where they are, and how they’re represented):
      • Bubble size for size of transfer
      • Color hue denoting transfer or out of team
      • Position for date close to transfer window
    • Data Types (Quantitative, Qualitative, Categorical, Continuous, etc.):
      • Qualitative and categorial
    • Encodings (Shape, Color, Position, etc.):
      • Shape, position, size, color hue
  • What works well here?
    • Showing a small multiples type view for each team and their transfers
  • What does not work well and what would I improve?
    • Having the totals summary numbers on the side of the charts is a little unorthodox and unintuitive
    • Bubbles seem to be placed arbitrarily without thought to the y-axis, even though the x-axis has meaning
    • Not immediately clear why some players are featured and noted in tooltips versus those that are not
  • What is the data source?  Do I see any problems with how it’s cited/used
    • Seems to be original Guardian data collected about the English Premier League, but not as clearly stated as I’d like to expect
  • Any other comments about what I learned?
    • Example of something pleasing to the eye in terms of color hue and perhaps some flash factor, but perhaps not that functional to explore upon closer examination.
      • Certainly sense for the purposes of the Guardian though in putting out this story and is a technique I’d borrow if I had a use case
      • Good for showing a bigger picture view
    • Probably not worth it in terms of the work it would be taken incrementally as filters are difficult to work and can be computationally expensive, but the nerd in me would have liked to search for the player
