Figure 8.
The image presents a Pareto chart for geographical barriers labelled G B 1, G B 2, and G B 3. The horizontal axis lists the barriers, and the left vertical axis shows the frequency of occurrence from 0 to 10. G B 1 has a frequency of 9, G B 2 also has a frequency of 9, and G B 3 has a frequency of 7. A cumulative percentage line rises from about 35 percent at G B 1 to around 75 percent at G B 2 and reaches 100 percent at G B 3. An orange dashed reference line marks approximately 80 percent on the cumulative percentage scale shown on the right vertical axis.Pareto analysis of (i) geographical barriers
