During April 2025, Mengyuan Cao updated the documentation for the antvis/GPT-Vis repository, focusing on aligning the README with the latest live demo video asset. Using Markdown and leveraging strong documentation skills, Mengyuan ensured that the reference to the demo accurately reflected current product capabilities, which improved user onboarding and reduced confusion for new users. The update was delivered as a single, traceable commit, emphasizing clarity and maintainability in the project’s documentation workflow. While no bugs were addressed during this period, the work demonstrated attention to release-readiness and supported better alignment between product features, marketing, and support activities.
