In this graph, there are a number of flaws:
- A PIE CHART. Pie charts should almost never be used. There are
virtually no circumstances where a pie-chart is better than a simple table
or a simple bar chart. The major problem with pie charts is that people have
a difficult time comparing slices of the pie.
- Pie is distorted by tilting and 3-D effects.
- Slices are not properly made. Why is the 6% slice wider than the 8% slice?
- Ducks.
This pie chart used an enormous amount of space to display just 5 numbers!
