D3：复杂有向无环图的高效可视化（项目依赖）
D3: Efficient visualization of a complex directed acyclic graph (project dependencies)
我目前正在探索一个包含许多独立项目和相互依赖关系的大型专有代码库。为了获得更好的概述，我想创建依赖关系的图形表示，这些依赖关系由有向无环图表示。希望最终能更好地理解依赖集群，并（利用对单个项目内容的了解）帮助重构项目和依赖关系。
目前，我正在使用 D3 进行可视化。下面是我当前尝试的完整代码（项目名称替换为虚拟名称）。如您所见，它看起来仍然很乱。将鼠标悬停在项目节点上时可以看到一些顺序。
我已经看过（但还没有尝试）d3-dag，这可能很有希望，但仅包含数据集相当小的示例。
我也想过使用 hierarchical edge bundling 之类的图表，但这里并没有真正的层次结构。
有没有人推荐比当前使用的力模拟布局更好的方法？

根据@Coola 的评论，我扩展了最近使用 Sankey 图进行的尝试，添加了填充和缩放功能以及在不同可视化模式之间切换的可能性。此外，我在力模拟方法中添加了一些 link 绘图样式，试图类似于捆绑电线以防止混乱。
将此作为答案发布而不是编辑原始问题，因为更改相当大并且包含重大进展。希望，这没问题。
不过，如您所见，事情还是有点乱。因此，我仍然很乐意看到更多的想法。
目前，我确实觉得 Hierarchical Edge bundling 最适合这个问题。为了能够创建这样的图，我通过主项目与其依赖项之间的最短路径间接引入了一个人工层次结构。
分层边缘捆绑
强制布局
桑基图
遗憾的是，完整代码太大，无法发布。
使用networkX库，首先创建一个networkX图然后调用布局函数，我使用spectral_layout因为我觉得它是可视化DAGs的更好方式。布局函数将 return 具有 x,y 位置的节点名称字典。我在 python 中这样做，将字典转换为 json 并将 json 传递给 D3。
我目前正在探索一个包含许多独立项目和相互依赖关系的大型专有代码库。为了获得更好的概述，我想创建依赖关系的图形表示，这些依赖关系由有向无环图表示。希望最终能更好地理解依赖集群，并（利用对单个项目内容的了解）帮助重构项目和依赖关系。
目前，我正在使用 D3 进行可视化。下面是我当前尝试的完整代码（项目名称替换为虚拟名称）。如您所见，它看起来仍然很乱。将鼠标悬停在项目节点上时可以看到一些顺序。
我已经看过（但还没有尝试）d3-dag，这可能很有希望，但仅包含数据集相当小的示例。
我也想过使用 hierarchical edge bundling 之类的图表，但这里并没有真正的层次结构。
有没有人推荐比当前使用的力模拟布局更好的方法？

根据@Coola 的评论，我扩展了最近使用 Sankey 图进行的尝试，添加了填充和缩放功能以及在不同可视化模式之间切换的可能性。此外，我在力模拟方法中添加了一些 link 绘图样式，试图类似于捆绑电线以防止混乱。
将此作为答案发布而不是编辑原始问题，因为更改相当大并且包含重大进展。希望，这没问题。
不过，如您所见，事情还是有点乱。因此，我仍然很乐意看到更多的想法。
目前，我确实觉得 Hierarchical Edge bundling 最适合这个问题。为了能够创建这样的图，我通过主项目与其依赖项之间的最短路径间接引入了一个人工层次结构。
分层边缘捆绑
强制布局
桑基图
遗憾的是，完整代码太大，无法发布。
使用networkX库，首先创建一个networkX图然后调用布局函数，我使用spectral_layout因为我觉得它是可视化DAGs的更好方式。布局函数将 return 具有 x,y 位置的节点名称字典。我在 python 中这样做，将字典转换为 json 并将 json 传递给 D3。
