PROFILE
Tom
Worked on enhancing the Sankey diagram feature in the apache/echarts repository, focusing on improving sorting functionality and test coverage. Refactored the sorting logic to support descending order and preserve the original order, aligning the implementation with the sunburst.sort method and handling both null and 'desc' cases as recommended. Introduced a dedicated test file to expand automated testing, which increased reliability and reduced regression risk for complex Sankey layouts. Utilized JavaScript and TypeScript along with charting libraries to optimize layout behavior and maintainability, ensuring safer future refactors and enabling faster development cycles through improved test coverage and clearer feature behavior.

Apr 1, 2026April 2026 — Apache/echarts Sankey enhancements: Implemented a dedicated test file for the Sankey feature and refactored sorting to support descending order or preserving the original order, improving layout optimization and test coverage. Implemented the recommended sorting alignment with sunburst.sort, handling null and 'desc' cases. Key commits: 6418ca21c356a7eb937b794dc96ee79f3eb5b47d (feat(sankey): added dedicated test file) and c108d1f79d0b540fa88c5ef8b8b535ebc86fd9bf (fix(sankey): follow sunburst.sort method; only null and `desc` implemented as suggested). This work delivers more reliable rendering, stronger test coverage, and clearer behavior for complex Sankey layouts, contributing to reduced regression risk and better maintainability.
