The file structure is the same as the collapsible force graph here:
https://gist.github.com/mbostock/1062288

I think it is the same file, actually - readme.json

You're going to need that file (or a similar one of your own) to run the script.

Hi, Can I have two separate parents links for a child. In the below example doctor1 should have a link to Hospital which has only link to Group Practice1..
{
"name": "Hospital",
"children": [
{"name": "Group Practice1",
"children": [
{"name": "Doctor1"},
{"name": "Doctor2"},
{"name": "Doctor3"}
]
},
{"name": "Group Practice3"},

Is possible to change orientation of the tree? for example start in the bottom and grow to top? Amazing work!

Hi, Thanks. How do you add a new node from new json, like if I had a database query based upon my parent. Not asking for the database stuff, just how to add a new node in the toggleing function. Thanks again.

I have been trying to implement this tree because of the collapsible capabilities but have no success. I've been working on it for a couple days now (I'm new to d3) and have only been able to get this one http://bl.ocks.org/d3noob/8324872 to work. Whenever I try the collapsible version, only a blank screen appears. Do you have any ideas why this would be happening?

Thanks for the example, I use this with my own data. It works well.
But by default, it only show 3 nodes, I need to click all of them to expand the nodes.
Does it have a parameter to make all the nodes are expanded when I access the index.html.

What you need to run this example. I save both flare.json and index.html in same local folder in my computer. Opening index.html with browser does not open any chart. Does it need to be run with flask ??

Rohit, you need to do a couple of things to run successfully.

  1. Replace script tag with <script src="https://d3js.org/d3.v3.min.js"></script>
  2. https://github.com/d3/d3/wiki#local-development use the documentation to install http-server (npm install -g http-server) I assume you know about npm.

This looks awesome! But is there a way to run this locally without the need for a server? Trying to avoid the CORS issue but haven't been lucky so far when loading the data.

Thanks!
