    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 probably wasn't clear earlier.. I already modified the code to read my sample .json instead of the given flare.json. But how do I 'print' the extra fields ? for e.g. in Line 96, I concatenated title & name text(function(d) { return d.name+' , '+d.title; }) , but how do i add an image src ? I'd prefer each value to be in a new line.

    D3 is very flexible and you can customize your data as you want. There is a function you could add every html tag such as img the append() function. Just need to write this code d3.select("body").append("img") and you can change the attributes with attr(), So update our code like this: d3.select("body").append("img").attr("src",'srcPath+name'). There is a point that I have to mention you can create separated tags and change the position of them with attr("transform","translate("+x+","+y")" the x,y could be any position. You cannot add the img tag inside the svg.

    This link will help you to learn d3.js. Enjoy it.

    This is Great ! I have some more requirements - a search box which traverses to & highlights a particular node, and a frame on the right for more info like large photo,email & phone when a node is clicked. I found some search code here and this is a test jsfiddle I'm trying to tweak here. But it's beyond my knowledge, while probably take couple hours for you. Would you accept, say bitcoin, for working on this? Does this site have private messaging?

    @Mark, is there a way we can change this to show Organization chart vertically rather than horizontally.

    @Learning, see updated answer, essentially just reverse the xs and ys

    Those images look quite blurry. Do you know how to fix it?
  • Fr0zenFyr

    I just can't believe the amount of time/effort you put in this answer, I'd have just given a sample json and few short snippets for the OP to do his homework. By the way, I was here looking for a way to make the height of canvas fluid. Can you point me in right direction.

    @Flame113 you are right...the images do look quite blurry. I was able to fix this using viewbox. Check this out: stackoverflow.com/questions/29442833/svg-image-inside-circle

    @Mark can you please make this reversed direction chart to more customizable way..like we have to edit the name, position. we have to delete the nodes in the tree..we have to add new node to tree
