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 is a combination of two visual concepts. The red dot and green circle highlight the low colorectal cancer rates in general, while the bar graph embedded in the callout allows a focused presentation of the disparity in cancer rates.
Some weaknesses of this format are unclear reference points for the bar graph (where is the 0 level?) and ambiguity regarding what exactly the red dot within the green circle signifies (89.7 vs. 113.5).
