理解 Hierarchical Edge Bundling json 数据集构建

Question

我想了解如何构建数据集以通过分层边缘捆绑进行可视化。

这是我的测试数据集

  [
        {"name":"Flare.Expertise.Informatics","imports":["Flare.Expertise.Informatics.Programming","Flare.Expertise.Informatics.Networking","Flare.Expertise.Informatics.Security","Flare.Expertise.Informatics.BioInformatics","Flare.Expertise.LifeScience.Zoology","Flare.People.APerson","Flare.People.BPerson","Flare.People.CPerson","Flare.People.DPerson"]},
        {"name":"Flare.People","imports":["Flare.People.APerson","Flare.People.BPerson","Flare.People.DPerson"]},
        {"name":"Flare.Expertise.LifeScience","imports":["Flare.Expertise.LifeScience.Biology","Flare.Expertise.LifeScience.Zoology","Flare.People.APerson","Flare.People.CPerson"]},
        {"name":"Flare.Expertise.Informatics.Programming","imports":["Flare.People.APerson","Flare.People.BPerson"]},
        {"name":"Flare.Expertise.Informatics.Networking","imports":["Flare.People.APerson","Flare.People.DPerson"]},
        {"name":"Flare.Expertise.Informatics.Security","imports":["Flare.People.BPerson","Flare.People.DPerson"]},
        {"name":"Flare.People.BPerson","imports":["Flare.Expertise.Informatics.Security","Flare.Expertise.Informatics.Programming"]},
        {"name":"Flare.People.APerson","imports":["Flare.LifeScience.Zoology","Flare.Expertise.Informatics.Networking","Flare.Expertise.Informatics.Programming"]},
        {"name":"Flare.People.DPerson","imports":["Flare.Expertise.Informatics.Networking","Flare.Expertise.Informatics.Security","Flare.Expertise.Business.Commerce"]},
        {"name":"Flare.People.CPerson","imports":["Flare.Informatics.BioInformatics","Flare.LifeScience.Biology","Flare.Expertise.Business.Marketing"]},
        {"name":"Flare.Informatics.BioInformatics","imports":["Flare.People.CPerson"]},
        {"name":"Flare.LifeScience.Zoology","imports":["Flare.People.APerson"]},
        {"name":"Flare.Expertise.Business","imports":["Flare.Expertise.Business.Marketing","Flare.Expertise.Business.Commerce","Flare.People.CPerson","Flare.People.DPerson"]},
        {"name":"Flare.Expertise.Business.Commerce","imports":["Flare.People.DPerson"]},
        {"name":"Flare.LifeScience.Biology","imports":["Flare.People.CPerson"]}
        ]

所以有 2 个主要类别

Flare.Expertise
Flare.People

Flare.Expertise 有 3 个主要类别：信息学、生命科学、商业。每个子类别都有进一步的类别，例如生命科学：动物学和生物学

Flare.People 有 4 个人：APerson、BPerson、CPerson 和 DPerson

我需要展示所有人都有不同的专长。例如 CPerson 有关于生物信息学和生物学的信息。因此，一个人可能拥有不止一个主要类别的专业知识，然后是各个子类别

我正在尝试在 D3 Hierarchical bundling example 上实现算法。我收到一个错误 Uncaught TypeError: Cannot read property 'push' of undefined

我无法修复这个错误。如果我更改推送运算符，我会得到空白页。对我来说，问题似乎与数据集有关。我不明白数据集中的错误在哪里。所以，请帮我解决这个错误。否则，请告诉我如何在我的数据中可视化上述关系

Answer 1

我从这个博客中找到了解决方案

http://ianh.co/modeling-data-with-the-d3-js-bundle-layout/

据此，"imports" 中的所有类别都必须存在于 "name"。

通过它，我能够更正我的数据集并能够使用它。
