It’s Hard to Compare Shapes.
Which piece of the pie is bigger – and by how much? It’s hard to say because the human eye finds it very difficult to judge how much bigger one shape is than another.
Pie charts and three-dimensional shapes may look attractive, but they won’t do a good job of presenting your data because the viewer won’t be able to tell how much bigger one quantity is than another.
On the other hand, a simple bar graph makes it easy for readers to compare one line length to the next.
