Poor Graphic
Criticism
- Chartjunk: The columns are filled with distracting gradients.
- Data-Ink ratio: Much of the graphic is filled with useless patterns. The actual (overly large) pie charts occupy only a fraction of the graphic.
- Data Density: One pie chart per year seems a bit excessive for the amount of information they provide.
- The individual pie charts are virtually indistinguishable, making pie charts a rather poor choice in this context.
- The pie charts 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.
- There are four graph labels in different fonts with redundant information.
- The labels are not anywhere near the pie charts and have to be found to derive any meaning from the charts.
Improved Graphic
Improvements
- Market share changes visible over the years.
- Removed confusing and unnecessary backgrounds.
- Increased data-ink ratio.
- Labels are clearly visible next to the lines.
- Difference between market shares easy to determine. One can immediately see that Sotheby's is always ahead of Christie's by roughly the same margin.
