We were able to use this example here(https://bl.ocks.org/d3noob/43a860bc0024792f8803bba8ca0d5ecd) and achieve the Collapsible tree diagram. We are looking to have boxes in here instead of circles with text aligned inside it.
Below is the diagram which we are trying to achieve using Version4.
Please let know what change needs to be done in the above code using d3 version 4 to achieve this
I have made necessary code changes to accommodate your requirement.
Hope it helps you.

I am new to D3 and trying to combine two examples from bl.ocks.org to add tooltips to the nodes of an interactive tree diagram. You can see the original code here: http://bl.ocks.org/d3noob/8375092 & http://bl.ocks.org/d3noob/a22c42db65eb00d4e369 .
I believe my issue stems from not knowing how to attach the .on("mouseover") portion to the nodes div. The current code does not render any output. Any help is greatly appreciated.

I am trying to find specific nodes on the tree layout. I found this example on plunkr:
function collapse(d) {
if (d.children) {
d._children = d.children;
d._children.forEach(function(d1){d1.parent = d; collapse(d1);});
d.children = null;
}}
function find(d, name) {
if (d.name == name){
while(d.parent){
d = d.parent;
click(d)
}
return;
}
if (d.children) {
d.children.forEach(function(d){find(d, name)});
} else if(d._children){
d._children.forEach(function(d){find(d, name)});
}}
[root].forEach(collapse);
var name = "layout"
find (root, name)
update(root);
http://plnkr.co/edit/Ce5Ub8PWXblSMcrYlkHa?p=preview which finds a specif node given a name. I adopted it to find a node given an ID.I have two problems with the implementation:
1- The code generates an error in the console "Error: attribute transform: Expected number, "translate(undefined,undefi…". Which I think is due to the x and y coordinates becoming null, but I cannot identify the exact condition. This error appears in the original example as well.
2- If I call the find routine once (by clicking the find button which calls find_name() and commenting out the second call to the find function) , it works, however if I call it more than once (by un-commenting and enabling the second call to find), the tree collapses to the root node.
Any help in understanding this behavior is much appreciated.

The reason for the error in the first question "The code generates an error in the console "Error: attribute transform: Expected number, "translate(undefined,undefi" is due to the SID being character. I converted it to integer and no error is generated.
I'm new to d3js and javascript in general. I am trying to create a tree of more than 8000 nodes, and used the basic tree examples available and modified to display vertically.
Example data is hard coded, however, on my local server, I read the data from an external JSON file.
I would like to be able to specify the depth level to start with (collapse all node deeper than 2) and allow the user to further expand or collapse nodes.
I tried modifying the "collapse" function to check for the depth level, however, the logic is not correct.
Appreciate any help in this regard.

You have to provide an else if condition, in case the if condition is falsy:
function collapseLevel(d) {
if (d.children && d.depth > 1) {
d._children = d.children;
d._children.forEach(collapseLevel);
d.children = null;
} else if (d.children) {
d.children.forEach(collapseLevel);
}
}
Here is your code with that change:
var data =[{"sid":"1","parent":"null","name_ar":"Hashim"},{"sid":"2","parent":"1","name_ar":"wahb"},{"sid":"3","parent":"1","name_ar":"Abdulmuttaleb"},{"sid":"4","parent":"2","name_ar":"Amina"},{"sid":"5","parent":"3","name_ar":"Abutaleb"},{"sid":"6","parent":"3","name_ar":"Abdulla"},{"sid":"7","parent":"3","name_ar":"Abbas"},{"sid":"8","parent":"3","name_ar":"Hamza"},{"sid":"9","parent":"6","name_ar":"Mohammed (Prophet)"},{"sid":"10","parent":"9","name_ar":"Alqassim"},{"sid":"11","parent":"9","name_ar":"Um Kalthoum"},{"sid":"12","parent":"9","name_ar":"Zainab"},{"sid":"13","parent":"9","name_ar":"Ruqaya"},{"sid":"14","parent":"9","name_ar":"Fatima"},{"sid":"15","parent":"9","name_ar":"Ibrahim"},{"sid":"16","parent":"9","name_ar":"Abdulla"},{"sid":"17","parent":"9","name_ar":"Muhsen"},{"sid":"18","parent":"5","name_ar":"Ali"},{"sid":"19","parent":"18","name_ar":"Hassan"},{"sid":"20","parent":"18","name_ar":"Hussain"},{"sid":"21","parent":"20","name_ar":"Ali Zain Alabbideen"},{"sid":"22","parent":"21","name_ar":"Mohammed Baqer"},{"sid":"23","parent":"22","name_ar":"Jafar Sadeq"},{"sid":"24","parent":"23","name_ar":"Mousa Kadim"},{"sid":"25","parent":"24","name_ar":"Ali AlAreed"},{"sid":"26","parent":"24","name_ar":"Ibrahim Murtada"},{"sid":"27","parent":"26","name_ar":"Mousa (the second)"},{"sid":"28","parent":"27","name_ar":"Ahmed"},{"sid":"29","parent":"28","name_ar":"Hussain"},{"sid":"30","parent":"29","name_ar":"Abu Alqassim Mohammed"},{"sid":"31","parent":"30","name_ar":"Najm Aldeen Mahdi"}];

PS: I changed to d.depth > 1 because it seems to me that you want to show 2 depths by default, not 3. If I'm wrong, just change that number accordingly.
I am using the collapsible tree in d3js and want to create the functionality that the text of the children will always be on the right hand side of the node and the text the parent will be on the left hand side.
And this updates every time a node is clicked.
the text attr are set in the chunk below.
nodeEnter.append("text")
.attr("x", function(d) { return d.children || d._children ? -10 : 10; })
.attr("dy", ".35em")
.attr("text-anchor", function(d) { return d.children || d._children ? "end" : "start"; })
.text(function(d) { return d.name; })
.style("fill-opacity", 1e-6);
Two things are required. You modify the x position and anchor based just on children being available (and not hidden children):
.attr("text-anchor", function(d) {
return d.children ? "end" : "start";
})
You also need to move the position to the update selection so it'll do it on redraw:
nodeUpdate.select("text")
.style("fill-opacity", 1)
.attr("text-anchor", function(d) {
return d.children ? "end" : "start";
})
.attr("x", function(d) {
return d.children ? -10 : 10;
});
Here's some full running code.
