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.

@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 ?

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 ?
