During March 2025, Jinqi developed a new line chart infographic example for the VisActor/VStory repository, visualizing temperature changes across Spring solar terms. The work involved front-end development using JavaScript to create interactive code demos that highlight data visualization techniques. Jinqi also authored comprehensive documentation in both English and Chinese, ensuring accessibility for a broader audience and providing clear guidance on using the new feature. The project focused on enhancing the repository’s data visualization examples, with careful attention to documentation quality and user experience. While the contribution was limited to a single feature, the implementation demonstrated depth in both technical and communication skills.
