Worked on the ppy/osu repository to enhance the Ranked Play Rating Graph, focusing on improving visual accuracy and user experience. Used C# and data visualization techniques to implement dynamic x-axis division sizing and precise left-edge alignment of bars, ensuring that rating intervals are accurately represented. Extended the cumulative rating line to match the updated axis range, providing a more complete and trustworthy visual for users. Refactored the rendering logic to improve code readability and maintainability, simplifying complex constructs while leaving room for future optimization. The work contributed to clearer, more engaging rating visuals within the context of game development.
