Excel Sheet: Obesity Prevalence By State

Excel Sheet Obesityxlsxsheet1stateoverall Obese Prevalence Rateobese

Write a Java Swing GUI program that reads data from two Excel files: one containing obesity rates for different states and racial groups, and another containing median income for each state. The program should provide four options to the user: plot overall obesity rate, obesity rate for White individuals, Black individuals, and Hispanic individuals versus median income. The selected option should generate a scatter plot showing the correlation between median income and the selected obesity rate across all states. Include functions for resetting the plot and exiting the program.

Obesity has become a critical public health issue in the United States, with various factors influencing its prevalence, including socioeconomic status and race/ethnicity. To understand these complex relationships, visualization tools such as scatter plots are invaluable, providing visual insights into potential correlations between economic indicators like median income and health outcomes like obesity rates. Developing a Java application with a graphical user interface (GUI) that reads relevant data from Excel files and visualizes these correlations can facilitate research, policy-making, and public awareness initiatives.

This paper presents the design and implementation of a Java Swing application that reads two Excel datasets—one listing obesity prevalence rates across states categorized by race and another detailing each state's median income—and enables users to generate scatter plots correlating median income with different obesity metrics. The application offers four options: plotting overall obesity rates, rates for White individuals, Black individuals, and Hispanic individuals, allowing comparative analysis of how income disparities relate to obesity among different racial groups.

The core functionality involves reading data from Excel files, which contain structured information with states as identifiers, and then aligning this data based on the state name to perform correlation analysis. Java's Apache POI library is a suitable tool for reading Excel files programmatically, enabling data extraction into manageable data structures. The visualization of data is achieved through the Java Swing library, utilizing components such as JPanel and Graphics objects to draw scatter plots dynamically based on user input.

The application interface is designed with user experience in mind, providing four radio buttons or dropdown options corresponding to the four plot types, along with 'Reset' and 'Exit' buttons for ease of use. When a plot option is selected, the program retrieves the relevant obesity rates and median income data, processes it, and renders an interactive scatter plot. The 'Reset' function clears the current graph allowing for new selections, while 'Exit' terminates the application.

In developing this application, key challenges included ensuring accurate data parsing from Excel formats, handling missing or inconsistent data entries, and scaling the scatter plot axes appropriately to reflect data distributions. The implementation employs robust exception handling and data validation to maintain stability. The visualization employs scaling techniques to fit data points within the plotting area, and labels are added for clarity. Furthermore, the program maintains a modular structure, with separate classes or methods dedicated to data reading, data processing, plotting, and user interface management.

This integration of data processing and visualization demonstrates how programming can facilitate the analysis of public health data, revealing patterns and potential disparities in obesity prevalence relative to income. Such tools are essential for researchers and policymakers aiming to target interventions and address health inequalities effectively.
