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

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。

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.

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);

我不知道我是否可以称之为生产就绪，但是有jGABL。

查看蓝图:

蓝图是属性图数据模型的接口、实现、实现和测试套件的集合。蓝图类似于JDBC，但用于图形数据库。在TinkerPop开源软件堆栈中，蓝图作为基础技术用于:

管道:一个惰性的数据流框架

Gremlin:一种图遍历语言

框架:对象到图的映射器

熔炉:一个图形算法包

Rexster:图形服务器
