组织结构图 - 树形、在线、动态、可折叠、图片 - 在 D3 中
Organization chart - tree, online, dynamic, collapsible, pictures - in D3
我是 web-development 的菜鸟。我正在尝试创建一个 tree-like 分层公司组织结构图。 google 的 visualization chart and Mike Bostock's D3 Reingold tree.
我都试过了
我想要这些功能:
- 树结构:top-down (google) 或 left-right (D3)
- online/dynamic :可在浏览器中查看并能够从 json 读取数据(google & D3), 不是静态visio或者ppt图
- 可折叠:能够隐藏子树(两者)
- space-adjusting : 节点应填充可见区域,以减少滚动(仅限 D3)
- 属性:显示名称、标题和可能的图片(仅限 google)
上面我已经标记了哪个工具允许哪些功能,afaik。
我更喜欢D3版本因为它看起来很酷
我可以修改 .json 以包含其他字段(标题、url 到照片等)- 这里是 sample
我的问题是 - 如何修改 D3 code 以显示员工姓名,然后在下一行显示职位,也许还显示图片?
或者如果那不可行 - 我如何修改 google code 以自动调整间距,以便节点的所有 children 靠在一起,并且我不必水平滚动?
如果您想使用 D3js 创建项目,只需使用 this 中的 script
代码并将 d3.json("/mbostock/raw/4063550/flare.json", function(error, flare)
替换为:
d3.json("yourJsonFile/jsonFileName.json", function(error, flare)
jsonFileName.json
是您自定义的 json 文件,就像这样 sample。
您也可以将图片名称插入 json 文件并用它替换 img
标签 src。
这是一个快速 example. It modifies this example,用于添加名字、姓氏、标题和照片。
