During October 2025, Bobby Xng focused on improving data visualization accuracy and reproducibility within the PyPSA/PyPSA repository. He addressed a key bug in the explore.ipynb notebook by correcting plotting parameters and refining grouping logic, ensuring that visual outputs accurately reflected the intended analytics. Bobby updated notebook metadata to align with the required Python version, which improved environment compatibility and reduced runtime issues. His work involved adjusting groupby arguments and parameter names for line and link widths, directly impacting the clarity of downstream reporting. Throughout this period, he applied his expertise in Python, Jupyter Notebook, and data visualization techniques.
