JGraphT是一个非常简单而强大的Java图形库，它做得非常好，为了消除任何困惑，它与JGraph不同。一些示例代码:

UndirectedGraph<String, DefaultEdge> g =
        new SimpleGraph<String, DefaultEdge>(DefaultEdge.class);

    String v1 = "v1";
    String v2 = "v2";
    String v3 = "v3";
    String v4 = "v4";

    // add the vertices
    g.addVertex(v1);
    g.addVertex(v2);
    g.addVertex(v3);
    g.addVertex(v4);

    // add edges to create a circuit
    g.addEdge(v1, v2);
    g.addEdge(v2, v3);
    g.addEdge(v3, v4);
    g.addEdge(v4, v1);

在一个大学项目中，我摆弄了yWorks的yFiles，发现它有很好的API。

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.

在可视化方面，我们小组取得了一些成功。我们扩展了它来处理建筑地板和气泡图，它没有太多抱怨。他们也推出了一个新的Flex工具包，叫做Flare，它使用了非常相似的API。

更新: 我不得不同意这个评论，我们最终写了很多自定义功能/围绕prefuse限制工作。我不能说从头开始会更好，因为我们能够从第一天开始使用prefuse来演示进度。另一方面，如果我们正在做相同东西的第二个实现，我可能会跳过prefuse，因为我们会更好地理解需求。

Apache Commons提供了Commons -graph。在http://svn.apache.org/viewvc/commons/sandbox/graph/trunk/下可以查看源代码。SVN中也有API使用示例。参见https://issues.apache.org/jira/browse/SANDBOX-458获得实现的算法列表，并与Jung, GraphT, Prefuse, jBPT进行比较

JGraphT是一个实现了许多算法的图库，并且(在我看来)有一个很好的图模型。Helloworld例子。许可:LGPL + EPL。

JUNG2 is also a BSD-licensed library with the data structure similar to JGraphT. It offers layouting algorithms, which are currently missing in JGraphT. The most recent commit is from 2010 and packages hep.aida.* are LGPL (via the colt library, which is imported by JUNG). This prevents JUNG from being used in projects under the umbrella of ASF and ESF. Maybe one should use the github fork and remove that dependency. Commit f4ca0cd is mirroring the last CVS commit. The current commits seem to remove visualization functionality. Commit d0fb491c adds a .gitignore.

Prefuse使用矩阵结构存储图，这对于稀疏图来说内存效率不高。许可:BSD

Eclipse Zest内置了图形布局算法，可以独立于SWT使用。看到org.eclipse.zest.layouts.algorithms。所使用的图结构是Eclipse Draw2d中的一个，其中节点是显式对象，而不是通过泛型注入的(这发生在Apache Commons graph、JGraphT和JUNG2中)。

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/
