Worked on the mne-python repository to address a targeted issue in the connectivity circle plot, focusing on improving the accuracy and readability of node label orientation within the 0–90° polar range. Delivered a concise, well-documented patch that corrected label display, enhancing the reliability of data visualization and reducing the risk of misinterpretation in connectivity analyses. Collaborated effectively with co-authors and maintained alignment with repository standards and pull request guidelines. Utilized Python for implementation, applying data visualization techniques and unit testing to ensure code quality. The work prioritized correctness and user experience, with no new features introduced during this period.
