Worked on the antvis/GPT-Vis repository, delivering a targeted bug fix to improve compatibility with the G2 v5 charting library. Addressed a container handling issue by enabling the container parameter to accept either a DOM element or an ID, aligning with G2 v5 requirements and preventing runtime errors during chart rendering. Updated supporting documentation and code examples to reflect the new container selector format, making onboarding and usage clearer for other developers. Collaborated across teams to ensure the fix was robust and well-documented. Utilized JavaScript and TypeScript, applying front end development and chart visualization expertise throughout the process.
