Happy New Year!

It's a distorted pie chart with some kind of 3D hemispherical add-on, or it's a cross-sectional chart with the top of a sphere lopped off.
Charts of the USA Today variety do not usually feature here but this one has the aspiration to inform readers -- the chart appears on a web page that purports to correct some myths about shark attacks.
The biggest casualty of the shark attack is the ordering of the data labels. It is a brain teaser as to what criterion was used to order the pie slices: it's not the total number of accidents, nor the number of deaths, nor the death rate, nor alphabetical.
Since a death rate is usually defined as deaths / total accidents, not the other way round, even the numerical data labels is harder to read than necessary.
There are two primary questions this chart is intended to address: the prevalence of different types of shark attacks, and the death rate of each type of attack (as a proportion of reported accidents).
We try a scatter plot showing these two metrics, adding notes to point out where the interesting data is.
