当我在特定图表上运行 Graphviz 时，我得到

等等。由于某种原因，当图表只有 605 个节点时(如错误开头所示)，它尝试使用 57721 个节点。有没有办法让它停止，也许布局更糟糕？我也尝试过其他布局； neato 和twopi 造成了一切重叠的困惑，fdp 稍好一些，但仍然很糟糕，而 circo 似乎也挂了。 Graphviz 版本是 2.26.3(不幸的是，这是 Debian 稳定版的最新版本)。
最佳答案
我们解决了这个问题。 Debian 应该获得最新版本。 2.26 版本已经有 4 年多了。尝试从http://www.graphviz.org/Download_linux_ubuntu.php安装它
请注意，报告的节点数量包括为跨排名图的级别路由边而创建的虚拟(“虚拟”)节点。如果图形有很多“长”边，您可能会得到二次放大。这不是一个错误。
对于 605 个节点，我建议neato -Goverlap=false 或 -Elen=2 或 3 或 sfdp (它忽略边长，但似乎更能避免重叠)。
与|E| 〜= 3|V|您的图表不一定太密集或难以布局。
