适用于大型数据集的最快的力导向网络图形引擎是什么?

发布于 2024-10-28 11:33:42 字数 553 浏览 1 评论 0原文

目前,我们拥有一个动态更新的网络图,其中包含大约1,500 个节点2,000 个边。它不断增长。我们当前的布局引擎使用 Prefuse - 特别是力导向布局 - 使用大型服务器大约需要 10 分钟才能获得漂亮、稳定的布局。

我看过一点 GraphViz 的 sfpd 算法,但还没有测试过......

有更快的替代方案吗我应该看什么?

  • 我不关心节点和边的视觉外观 - 我们单独处理 - 只需将 x, y 放在节点上。
  • 我们确实需要能够修改图表特定部分的布局属性,例如,为某些节点应用特殊的更紧或更松的弹簧。

预先感谢,如果您需要更具体的信息来回答,请评论!

编辑:我特别寻找布局引擎选项之间的速度比较。基准、具体示例或个人经验就足够了!

We currently have a dynamically updated network graph with around 1,500 nodes and 2,000 edges. It's ever-growing. Our current layout engine uses Prefuse - the force directed layout in particular - and it takes about 10 minutes with a hefty server to get a nice, stable layout.

I've looked a little GraphViz's sfpd algorithm, but haven't tested it yet...

Are there faster alternatives I should look at?

  • I don't care about the visual appearance of the nodes and edges - we process that separately - just putting x, y on the nodes.
  • We do need to be able to tinker with the layout properties for specific parts of the graph, for instance, applying special tighter or looser springs for certain nodes.

Thanks in advance, and please comment if you need more specific information to answer!

EDIT: I'm particularly looking for speed comparisons between the layout engine options. Benchmarks, specific examples, or just personal experience would suffice!

我编写了一个基于 JavaScript 的图形绘制库 VivaGraph.js

它计算布局并在大约 10-15 秒内渲染具有 2K+ 顶点、8.5K 边的图形。如果您不需要渲染部分,它应该会更快。

以下是演示其实际操作的视频:使用 VivaGraphJS 进行 WebGL 图形渲染

在线演示可在此处获取。观看演示需要 WebGL,但计算图形布局不需要 WebGL。该库还可以在 node.js 下工作,因此可以用作服务。

API 使用示例(仅布局):

var graph = Viva.Graph.graph(),
    layout = Viva.Graph.Layout.forceDirected(graph);

graph.addLink(1, 2);
layout.run(50); // runs 50 iterations of graph layout

// print results:
graph.forEachNode(function(node) { console.log(node.position); })

希望这有帮助:)

I wrote a JavaScript-based graph drawing library VivaGraph.js.

It calculates layout and renders graph with 2K+ vertices, 8.5K edges in ~10-15 seconds. If you don't need rendering part it should be even faster.

Here is a video demonstrating it in action: WebGL Graph Rendering With VivaGraphJS.

Online demo is available here. WebGL is required to view the demo but is not needed to calculate graphs layouts. The library also works under node.js, thus could be used as a service.

Example of API usage (layout only):

var graph = Viva.Graph.graph(),
    layout = Viva.Graph.Layout.forceDirected(graph);

graph.addLink(1, 2);
layout.run(50); // runs 50 iterations of graph layout

// print results:
graph.forEachNode(function(node) { console.log(node.position); })

Hope this helps :)

我会看看 OGDF,特别是 http://www.ogdf.net/ doku.php/tech:howto:frcl
我没有使用过 OGDF,但我确实知道快速多极多级是一种性能良好的算法,当您处理涉及力导向布局的运行时类型以及所需的节点数量时,这非常重要。
除其他原因外,为什么该算法很棒:快速多极子方法。快速多极方法是一种矩阵乘法近似,它可以在较小程度上减少矩阵乘法近似的 O() 运行时间。理想情况下,您应该拥有如下代码: http://mgarland.org/files/papers /layoutgpu.pdf 但我在任何地方都找不到它;也许 CUDA 解决方案无论如何都不适合你。

祝你好运。

I would have a look at OGDF, specifically http://www.ogdf.net/doku.php/tech:howto:frcl
I have not used OGDF, but I do know that Fast Multipole Multilevel is a good performant algorithm and when you're dealing with the types of runtimes involved with force directed layout with the number of nodes you want, that matters a lot.
Why, among other reasons, that algorithm is awesome: Fast Multipole method. The fast multipole method is a matrix multiplication approximation which reduces the O() runtime of matrix multiplication for approximation to a small degree. Ideally, you'd have code from something like this: http://mgarland.org/files/papers/layoutgpu.pdf but I can't find it anywhere; maybe a CUDA solution isn't up your alley anyways.

Good luck.

Gephi Toolkit 可能正是您所需要的:一些布局速度非常快,但质量很好:http://gephi.org/ toolkit/

30 秒到 2 分钟足以布局这样的图表,具体取决于您的机器。
您可以使用 ForAtlas 布局或 Yifan Hu 多级布局。

对于非常大的图(+50K 节点和 500K 链接),OpenOrd 布局将

The Gephi Toolkit might be what you need: some layouts are very fast yet with a good quality: http://gephi.org/toolkit/

30 secondes to 2 minutes are enough to layout such a graph, depending on your machine.
You can use the ForAtlas layout, or the Yifan Hu Multilevel layout.

For very large graphs (+50K nodes and 500K links), the OpenOrd layout wil

在商业场景中,您可能还想查看 yFiles 图形布局和可视化库系列。

甚至它的 JavaScript 版本 也可以使用不同的排列样式对数千个节点和边进行布局。 “有机”布局样式是强制导向布局算法的一种实现,本质上类似于 Neo4j 浏览器应用程序中使用的算法。但是还有更多可用的布局算法可以为某些类型的图形结构和图表提供更好的可视化效果。根据问题的设置和结构,某些算法只需几秒钟,而更复杂的实现也可能使您的 JavaScript 引擎崩溃。截至目前,基于 Java 和 .net 的变体的性能仍然要好一些,但 JavaScript 引擎正在迎头赶上。

您可以在 这个在线演示中使用这些算法和设置

免责声明:我为 yWorks 工作,该公司是这些库的创建者,但我并不代表我的雇主。

In a commercial scenario, you might also want to look at the family of yFiles graph layout and visualization libraries.

Even the JavaScript version of it can perform layouts for thousands of nodes and edges using different arrangement styles. The "organic" layout style is an implementation of a force directed layout algorithm similar in nature to the one used in Neo4j's browser application. But there are a lot more layout algorithms available that can give better visualizations for certain types of graph structures and diagrams. Depending on the settings and structure of the problem, some of the algorithms take only seconds, while more complex implementations can also bring your JavaScript engine to its knees. The Java and .net based variants still perform quite a bit better, as of today, but the JavaScript engines are catching up.

You can play with these algorithms and settings in this online demo.

Disclaimer: I work for yWorks, which is the maker of these libraries, but I do not represent my employer on SO.

我会看一下 http://neo4j.org/ 它的开源代码,这对您的情况有益,这样您就可以根据您的需求进行定制。 github 帐户可以在此处找到。

I would take a look at http://neo4j.org/ its open source which is beneficial in your case so you can customize it to your needs. The github account can be found here.
