Worked on improving documentation accuracy for the Radar component in the apache/echarts-doc repository, focusing on aligning guidance with recent API changes. Addressed a documentation bug by updating both English and Chinese docs to replace the deprecated 'nameGap' property with the new 'axisNameGap' terminology. This update, implemented using Markdown and documentation best practices, aimed to reduce user confusion and streamline onboarding for new contributors. The work ensured consistency across languages and maintained clear traceability through detailed commit messages. By prioritizing clarity and alignment with the current API, the changes helped lower support overhead and improved the overall user experience.
