The "sausage" (worst. name. ever. :-) ) solve some of the problems, but not all of them. With enough slices, it's not always clear which is larger than which.

The "sausage" (worst. name. ever. :-) ) solve some of the problems, but not all of them. With enough slices, it's not always clear which is larger than which. Depending on what the viewer wants/needs, often a humble bar or column chart would be more effective. The sausage and the pie both do a decent job with just a few slices (the sausage is definitely an improvement), but both break down with a lot of slices.
