是否有Cytoscape的布局扩展名，可实现类似于Neo4j浏览器的动态行为，即拖动节点时，其边缘具有一定的弹性，但还沿部分路径拖动连接的节点（我称之为局部重力）？
更新：
我正在使用的示例使用CoSE Bilkent (compound) layout extension，但似乎不支持我开箱即用后的效果/动画。我曾希望scarcely documented { gravity: 1 }选项可能与之相关-毕竟，当一个节点将其他节点拉到一起时，这很可能被描述为重力-但更改小样本图上的设置没有这种关系影响;随后进行了一些挖掘，我现在认为设置与显示图形中心节点的距离有关。然后，我查看了所有layout demos，似乎没有一个显示出开箱即用后的效果。 AllegroViva似乎实现了类似的行为（video），但据我了解，它正在该视频中渲染一个时间序列（因此可能只是手动重绘该图）。他们的网站也似乎不存在。
我要寻找的是简单的东西，理想情况下是开箱即用的，或者可以快速实施的东西。不幸的是，我不确定我想要的搜索词是什么（尤其是在Cytoscape的域中）。因此，我问什么是公认的非常高级的问题。今天，我发现 Visjs称之为physics events （或至少使用了该演示中我所追求的效果）-但正如我提到的，在Cytoscape中，gravity显然不是我想要的。但是，此时，我仅试图确定Cytoscape是否是正确的库，或者是否需要查看其他对象，例如Alchemy (cf. its Philosophers' Relatedness example）。

谢谢您编辑问题，我想我可以为您提供帮助。 Cytoscape.js具有此功能，深埋在extension layouts中，尤其是在cytoscape.js-cola中。布局是具有“弹性”节点的物理布局，因此它们之间的距离保持不变。这里的问题是，作者在Notes段中对此进行了描述：
- 如果要保持交互性，则可能不应该将infinite：true与fit：true混合使用。贴合自然会更改缩放级别，使拖动未对齐，并给用户带来怪异的感觉，尽管它在技术上仍然可行。更好地适合：无限时为false：true，在layoutready上为cy.center（）或cy.fit（）。
- alignment选项不像原始的Cola选项那样灵活。在这里，只能使用整数来指定相对位置，因此它有一定的局限性。如果您希望看到更复杂的实现，请发送拉取请求。
因此，此示例应该起作用（请注意，节点可以移动，但是由于它们已经处于最佳位置，它们倾向于保持编队状态）：
document.addEventListener("DOMContentLoaded", function() {
var cy = (window.cy = cytoscape({
container: document.getElementById("cy"),

boxSelectionEnabled: false,

Cytoscape.js能够显示力的布局，但是比您提供的两个示例差一些（它们可以显示图形而无需将节点移动到最佳位置，但用户会首选）。如果您想使用cytoscape.js，可以很好地做到这一点，但是请始终考虑所需的用例，并检查是否有其他应用程序可以更好地处理这种情况（cytoscape.js具有很多很棒的功能可以使用，因此如果您能使其运作起来，那我将是cytoscape的最佳选择。
祝你好运！
答案 1 :(得分：1)
您可以使用d3.js的force-directed layout。这是example graph。
我相信Neo4j浏览器也使用d3.js
在官方网站上：
默认的Neo4j服务器具有基于内置D3.js库的功能强大的可自定义数据可视化工具。

我发现一个视频可能与您的问题Use of Cytoscape.js for Client project类似，另外还有一个扩展名为d3.js cytoscape.js-d3-force的扩展版LAYOUT。
