A line chart would be the best format to visually display the U.S. divorce rate over the last 50 years as it allows for the display of trends and changes over time. A histogram, although appropriate for displaying frequency distributions, would not effectively display changes in the divorce rate over time. Pie charts are not appropriate for interval-ratio variables, as they are best suited for categorical variables. The statement that "data in the form of rate should never be displayed in a chart or graph" is not accurate, as long as the appropriate chart or graph is chosen for the variable being displayed.
