Finding space for labels of small pie slices
In pie diagrams, the small pieces always come in last, and end up close to the top of the pie chart. Adding readable labels becomes difficult as the horizontal space for them is small.
I find it better to rotate the pie chart in such a way that the smaller pieces get in a horizontal position, so you have space to write out the labels of them. The illustration shows an example.
