If you were using JGraph, you should give a try to JGraphT which is designed for algorithms. One of its features is visualization using the JGraph library. It's still developed, but pretty stable. I analyzed the complexity of JGraphT algorithms some time ago. Some of them aren't the quickest, but if you're going to implement them on your own and need to display your graph, then it might be the best choice. I really liked using its API, when I quickly had to write an app that was working on graph and displaying it later.

试试Annas吧，它是一个开源的图形包，很容易掌握

我不知道我是否可以称之为生产就绪，但是有jGABL。

如果需要性能，可以看看Grph。该图书馆由法国大学和CNRS/Inria开发。

该项目是主动和被动的支持提供!

如果你喜欢图形算法，JDSL (Java中的数据结构库)应该足够好了——http://www.cs.brown.edu/cgc/jdsl/

提供了一个强大的软件来处理图形(直接或非直接)。还生成了Graphivz代码，可以看到图形表示。您可以将自己的代码算法放入包中，例如:回溯代码。该软件包提供了一些算法:Dijkstra，回溯最小路径代价等。
