Worked on the antvis/GPT-Vis repository, focusing on enhancing project documentation to improve user onboarding and clarity. Updated the README file to reference the latest live demo video asset, ensuring that documentation accurately reflected current features and the demo experience. This change aimed to reduce confusion for new users and align the documentation with ongoing marketing and support efforts. The update was implemented in Markdown, leveraging strong documentation skills to maintain release-readiness and traceability. All modifications were consolidated into a single, well-documented commit, emphasizing clarity of purpose and ease of future maintenance without introducing new features or bug fixes.
