每颗 star 和每个 fork 的添加时间，来自 GitHub 并按天汇总。累计增长位于其构成来源——每日新增——的正上方，二者可相互对照：稳定的自然增长与短暂的突增形态截然不同。当这一差别可被衡量时，它会作为增长真实性予以报告。

仅显示最近的历史——该仓库超出采集窗口，因此未采集最早的历史记录。

每个点涵盖 6 天。

来自 GitHub 依赖图的完整解析依赖集合：0 个直接依赖与 24 个间接（传递）软件包。仓库提交锁文件时，传递闭包才是完整的。

安装 pypi:nltk@3.10.0 会引入 5 个包（直接与传递）：其中 0 个存在已知公告，0 个为直接依赖。

没有已知公告影响已评估的依赖。

公告表示依赖图中记录的版本落入某条公告的受影响范围。可达性未经分析，且依赖图包含开发与测试的版本固定——某项发现可能只涉及工具链而非交付的软件。
