Worked on the antvis/G6 repository to deliver Nested Self-Loop Edge Support with Circular Edge Config Options, enhancing the library’s ability to represent complex graph structures. Leveraging JavaScript and Node.js, implemented configurable circular edges and addressed the calculation of target-end tangent directions to ensure accurate edge rendering. The approach included synchronizing updates across the codebase and associated demo sites, improving both maintainability and developer experience. Focused on front end development and graph theory, the work expanded the modeling expressiveness of G6 while refining pull request and issue workflows, resulting in a more robust and user-friendly graph visualization tool.
