Poor Graphic
Criticism
- 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.
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.
