A scatter diagram is a type of plot used to display the relationship between two variables. By plotting the data points on a scatter diagram, it becomes easier to identify any outlier pairs of points, which can then be excluded or dealt with appropriately. Using a pie chart or a cluster diagram would not be appropriate for identifying outlier pairs of points, and while a spiral diagram could be used for this purpose, it is not a widely recognized or commonly used method.
