During April 2025, Andrew Crabtree contributed to the swosu/SwosuCsPythonExamples repository by preparing and refining a dataset for CS1 Spring 2025 data visualization. He initialized the 2025_sp_cs1.txt file with a placeholder entry, then enhanced data completeness by appending last names to existing first names, ensuring readiness for upcoming demos and analytics. His work focused on text-based data management and documentation, utilizing version control to track changes and maintain collaboration standards. While the scope was limited to two features and involved no bug fixes, the contributions improved dataset accuracy and supported the project’s goal of enabling effective data visualization for stakeholders.
