javascript - Organization chart - tree, online, dynamic, collapsible, pictures - in D3

I am a noob in web-development. I'm trying to create a tree-like hierarchical company org chart. I tried both google's visualization chart and Mike Bostock's D3 Reingold tree.

I want these features :

tree structure : either top-down (google) or left-right (D3)
online/dynamic : viewable in browser and able to read data from json (both google & D3), not static visio or ppt diagram
collapsible : able to hide subtrees (both)
space-adjusting : nodes should fill visible area, to reduce scrolling (only D3)
attributes : display name, title & possibly picture (only google)

Above I've marked which tool allows which features, afaik.
I prefer the D3 version because it looks cool.
I can modify the .json to include additional fields (title, url to photo etc.) - here is a sample

My question is - how do I modify the D3 code to display an employee's name, then title in the next line, and maybe picture too ?

Or if that's not feasible - how do I modify the google code to automatically adjust spacing, so that all children of a node are close together, and I don't have to horizontally scroll ?

I don't know D3.js well enough to answer your question there. I do know the Google Charts API pretty well, though, and... Let's just say that based on the way you've presented your question that changing the spacing on the org chart is not something you want to attempt. The rendered org chart is actually just a very complicated HTML Table with some fancy CSS applied to it. It's not very flexible. It would take some pretty crazy CSS or jQuery voodoo to get it to do anything other than what it already does. – nbering Commented Jun 19, 2015 at 2:15
@Balrog30 - yes, I want google charts to adjust the spacing automatically - I rephrased the question here with code samples. – d-_-b Commented Jun 19, 2015 at 2:29
What I mean to say is, in order to do what you're describing you'd be writing something nearly as complex as what the Google Charts API is doing to draw what it is now. I don't know much about D3, but I know it's open source and extensible. Google Charts is not. You're probably better off with D3.js in this case. Google Charts is great and easy to use as long as you're willing to live with what Google is giving you for free. – nbering Commented Jun 19, 2015 at 2:38

If you like to create your project with D3js, Just need to use the script codes from this and replaced3.json("/mbostock/raw/4063550/flare.json", function(error, flare) with this :

d3.json("yourJsonFile/jsonFileName.json", function(error, flare)

The jsonFileName.json is your customized json file like this sample. Also you can insert name of your pictures into the json file and replace the img tag src with it.
