I searched the web for the graph that you mentioned and found it on this website1. The graph shows the percentage of deaths by the four most common causes in 2014, as well as the percentage of deaths by all other causes. Here are some problems that I see with the graph:
The graph does not have a title or a source. This makes it unclear what the graph is about and where the data came from.
The graph does not have a legend or labels. This makes it difficult to identify which color corresponds to which cause of death.
The graph does not have a scale or units. This makes it impossible to compare the exact values of the percentages or to calculate the total number of deaths.
The graph uses a 3D pie chart, which distorts the proportions and angles of the slices. This makes it misleading and inaccurate to compare the relative sizes of the slices.
A better way to present the data would be to use a 2D pie chart with a title, a source, a legend, labels, a scale, and units. Alternatively, a bar chart or a table could also be used to show the data more clearly and accurately.
I hope this helps you understand the problems with the graph. Like if it helped ‼️
