The human resources department wants to understand the relationship between the ages and incomes of all employees. Which of the following graphics is the most appropriate to present the analysis?

A scatter plot is ideal for displaying the relationship between two continuous numerical variables, like age and income. Each point on the plot represents an employee's age and corresponding income, allowing for visual identification of trends, correlations, or clusters between these two variables.

An area plot is typically used to show how quantities change over time or categories, often with stacked areas to represent parts of a whole, not for relationships between two continuous variables.

A bar chart is used to compare discrete categories or show changes over time for categorical data, not for visualizing the relationship between two continuous variables.

A pie chart is used to show proportions of a whole for categorical data, making it unsuitable for analyzing the relationship between two numerical variables.
