Problem: New contributors often struggle to understand large, complex codebases when trying to contribute to Wikimedia projects. Navigating multiple versions, issues, and commit histories can be overwhelming, especially for beginners.

Proposed Solution: To address this, I plan to develop a tool that visualizes Wikimedia codebases through data flow diagrams and relational diagrams. These diagrams will offer both high-level and low-level overviews of the code, making it easier for new contributors to understand how the project functions and where they can contribute.

Benefits: This tool will cut down onboarding time, reduce confusion, and help new contributors resolve issues faster. By simplifying the process, contributors will be able to make meaningful contributions more quickly, leading to quicker problem resolutions and fewer pull request revisions.

Session Overview: In my session, I will demonstrate how this tool will benefit Wikimedia's community and present strategies for building and implementing these diagrams effectively.
