Citation graph visualisation is a useful tool for contextual awareness in academic research. Unfortunately, existing solutions can suffer from several drawbacks, such as a poor scaling, shallow network traversal, freemium gating, and slow build times. Oignon is a free, open-source tool for systematically exploring academic research. It uses a dual-path ranking system with recency weighting to create graphs capturing both foundational works and recent breakthroughs related to a specific publication.

翻译：引文图谱可视化是学术研究中实现情境感知的有用工具。然而，现有解决方案常存在若干缺陷，例如扩展性不足、网络遍历深度有限、采用免费增值模式限制功能，以及构建速度缓慢。洋葱是一款免费开源工具，用于系统性地探索学术研究。它采用具有时效性权重的双路径排序系统，能够生成同时涵盖特定出版物相关奠基性研究与最新突破的引文图谱。
