Poor Graphic

Sotheby's / Christie's Worldwide Sales Market Share Analysis

Critique

  • gradient-fill of the year-columns - unnecessary Chartjunk
  • six cakes for one data-row - very low Data Density
  • The individual pie charts are virtually indistinguishable, making pie charts a rather poor choice in this context.
  • cakes are arranged diagonally without any meaning (except for the growing years)
  • The position of the pie charts suggests an increase on the y-axis which doesn't have any function or labels.
  • 4 graph-labels in different font with redundant information
  • The labels are not anywhere near the pie charts and have to be found to derive any meaning from the charts.
