During June 2025, Haodong focused on improving documentation accuracy for the Radar component in the apache/echarts-doc repository. He updated both English and Chinese Markdown files to reflect the deprecation of the 'nameGap' property, renaming it to 'axisNameGap' in line with recent API changes. This work required careful attention to cross-language consistency and clear communication of the deprecation timeline, reducing potential user confusion and support requests. Haodong’s contribution centered on documentation skills and proficiency with Markdown, ensuring that onboarding and ongoing usage of the Radar component remained straightforward and aligned with the current state of the API.
