News stories often try to clarify disparities in disease risk across populations. E.g., the disease is more common in this group vs. that group. This display tries to convey not only that one group’s risk is more but also just how much more.
This graphic combines two standard graph types in a novel way. The icon array of dots on the bottom represents the full population of 100,000 people. (Each dot represents 200 people.) One of those dots is expanded out into the line graph along the top of each section. This allows the disparity in disease rates to be highlighted while simultaneously clarifying how small the overall risk is.
