圆点边缘生成过长，60边缘

Question

我试图使用SchemaCrawler从Oracle数据库获取MPD。 该工具生成一个点文件，然后使用点生成图形。

但一个小时后，该处理还是didnt完成，所以我尝试推出自己点上我用下面的命令文件点：

点-v -Tpng schemacrawler.7007049984130928063.dot> graph.png

在下面的点文件中，我尝试减少边缘的数量和大约60个边缘，它持续2分钟，因为它永远不会结束。 =>文件：http://pastebin.com/Wvup5NTF

我得到以下跟踪：

C:\dev\softs\schemacrawler-oracle-10.08.02>dot -v -Tpng schemacrawler.7007049984130928063.dot > graph.png 

dot - graphviz version 2.30.1 (20130214.1330) 

libdir = "C:\dev\softs\graphviz" 

Activated plugin library: gvplugin_pango.dll 

Using textlayout: textlayout:cairo 

Using render: cairo:cairo 

Using device: png:cairo:cairo 

Activated plugin library: gvplugin_dot_layout.dll 

Using layout: dot:dot_layout 

The plugin configuration file:... 

network simplex: 28 nodes 80 edges maxiter=2147483647 balance=2 

在此之后，没事。 有没有办法让它更快，并且能够管理如此多的节点和边缘（从我的观点来看，这并不高）？

谢谢

尝试更新您的Graphviz。我试过这个文件，它对我来说工作得很好。下面是详细的输出：
