@ikiril01 While this is a bit later and I haven't worked on it at all, if you look at the click function and how that works, you might be able to try this:
on load, set all elements attribute _children to their children, and set children to null
and then from there, it may just work as you want.
I tried this in different places in the code and no luck!
Idea is to have the large trees start as 100% collapsed
nodes.forEach(function(n,i,d) {
if ( d.children ) {
d._children = d.children;
d.children = null;
update(d);
}
});
Try:

Check the moveChildren function.
What is the purpose of the "size" field in all the children and how does this size change the layout/performance of the tree ?
Guys i tried all these codes with index.html and flare.json in the same folder and it displays nothing. Can you please help, did i forget to install something to see it?
Do you have a web server running?
is there any way to make the height of each bar dynamic based on the length of content?
Did anyone get this running for v4? I am currently struggling with this, as i am apparently not proficient enough with d3 yet, to get it working.
is there a way to make the width of the rectangle dynamic based on the value of node ?
Thanks for sharing.. Is there a possibility to search a term (using a drop down) and collapse specific tree section. Is there any example available?
This is great! Is there any way to have all nodes collapsed when first loading the view? Otherwise, it becomes quite difficult to navigate large trees effectively.
Hi I've found a way to collapse the tree down to the main nodes:
Add this function:
function collapse(d) {
if(d.children) {
d._children = d.children
d._children.forEach(collapse)
d.children = null
}
}
And call it as follows before you update root:
root.children.forEach(collapse);
update(root);
