用于创建和布局交互式图形（节点和箭头）的 Javascript 框架
是否有任何 JavaScript 框架支持创建交互式节点和箭头？
我希望能够定义节点（带有一些图形和文本） 连接它们的（定向）箭头，箭头本身（或附近）也有文字。
我希望节点能够根据箭头的最小交集和可能的其他类型的提示自行渲染，例如为每个节点提供一个数字，并使数字较低的节点在显示中位于较高（或较低）的位置。
如果自动布局机制也支持修复某些节点的位置并仅布局非固定节点的能力，那就太好了。
节点和箭头应该根据需要选择可拖动和可单击的触发事件。
如果我找不到更好的东西，我会使用 raphael。但很乐意为自己节省一些编码时间。
Are there any javascript frameworks out there that support creating of interactive nodes and arrows ?
I would like to be able to define nodes (with some grahics and text)
and (directed) arrows that connect them that also have text on the arrow itself (or near it).
I will want the nodes to be able to render them selves based on minimum intersections of arrows and possible other types of hinting, like providing a number to each node and having nodes with lower numbers be located higher (or lower) in the display.
It would eb also nice if the auto layout mechanism would also support the ability to fix the locations of some of the nodes and layout only the non-fixed ones.
nodes and arrows should be optionally drag-able and click-able firing events as required.
I will user raphael if I don't find anything better. but would be happy to save myself some coding time.
