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 cakes do not visualize clearly the change over the years.
• cakes are arranged diagonally without any meaning (except for the growing years)
• 4 graph-labels in different font with redundant information
