D3 js fit text inside each node

How can I wrap text inside each node making the node automatically resize, just as in css you would do with fit-content or display flex?
Here's the snippet, available at this link: https://codepen.io/boxxello/pen/XWYvRQO
or here:
css:
html, body {
margin: 0;
padding: 0;
background-color: rgb(140, 149, 226);
}
.node {
cursor: pointer;
}
.node circle {
}
.node-leaf {
}
.node text {
font: 10px sans-serif;
}
.link {
fill: none;
stroke: rgb(55, 68, 105);
stroke-width: 1px;
}
js:
var margin = {top: 20, right: 90, bottom: 30, left: 90},
width = 1300 - margin.left - margin.right,
height = 900 - margin.top - margin.bottom;
var svg = d3
.select("body")
.append("svg")
.attr("width", width + margin.right + margin.left)
.attr("height", height + margin.top + margin.bottom)
.append("g")
.attr("transform", "translate(" + margin.left + "," + margin.top + ")");
var i = 0,
duration = 750,
root;
var treemap = d3.tree().size([height, width]);
root = d3.hierarchy(treeData, function (d) {
return d.children;
});
root.x0 = height / 2;
root.y0 = 0;
root.children.forEach(collapse);
update(root);
function collapse(d) {
if (d.children) {
d._children = d.children;
d._children.forEach(collapse);
d.children = null;
}
}
function update(source) {
var treeData = treemap(root);
var nodes = treeData.descendants(),

nodes.forEach(function (d) {
d.y = d.depth * 180;
});

function diagonal(s, d) {
path = `M ${s.y} ${s.x}

${(s.y + d.y) / 2} ${d.x},
${d.y} ${d.x}`;
return path;
}
function click(d) {

d._children = d.children;
d.children = null;
} else {
d.children = d._children;
d._children = null;
}
update(d);
}
}
The part where you could change the style property is at:
.attr("width", function (d) {
return d.parent ? 40 : 20;
})
.attr("height", 20)
.classed("node-leaf", true);
Or at least is where I've tried to deal with it. The current version I'm using of d3js is the 4.2.2, I actually used this version it fitted my needs (found the snippet online and there have been breaking changes in the 7.* which is the current version) not because I didn't want to upgrade it (if it's easier in the newer versions please let me know.
This is an expected output, as you can see the node basically fits all the text inside it (I left the parent nodes blank because they're not relevant in this case, but they would need to do the same thing, so applying a property to all the nodes would be great.

How to invert direction of nodes in diagram in d3.js

So d3.js i am using to display a nodes diagram. right now parent start form left and children on right. is there any way to invert that direction so that children on left and parent on right.
Below is the function render tree which will display tree node. I call renderTree for example like vm.renderTree(vm.tree, "#tree-container");
vm.renderTree = function (treeData, treeId) {
var totalNodes = 0;
var maxLabelLength = 0;
var selectedNode = null;
var draggingNode = null;
var panSpeed = 200;
var panBoundary = 20;
var i = 0;
var duration = 750;
var root;
var viewerWidth = $(document).width();
var viewerHeight = $(document).height();
vm.tree = d3.layout.tree()
.size([viewerHeight, viewerWidth]);
var diagonal = d3.svg.diagonal()
.projection(function (d) {
return [d.y, d.x];
});
function visit(parent, visitFn, childrenFn) {
if (!parent)
return;
visitFn(parent);
var children = childrenFn(parent);
if (children) {
var count = children.length;
for (var i = 0; i < count; i++) {
visit(children[i], visitFn, childrenFn);
}
}
}
visit(treeData, function (d) {
totalNodes++;
if (typeof d.lename !== "undefined") {
if (treeId == "#tree-container-legalTree") {
maxLabelLength = Math.max(d.lename.length, maxLabelLength);
}
else {
maxLabelLength = Math.max(d.name.length, maxLabelLength);
}
}
}, function (d) {
return d.children && d.children.length > 0 ? d.children : null;
});
var sortTree = function () {
vm.tree.sort(function (a, b) {
if (typeof d !== "undefined") {
if (treeId == "#tree-container-legalTree") {
return b.lename.toLowerCase() < a.lename.toLowerCase() ? 1 : -1;

Replace d.y with height - d.y, swap positionning of text (start / end) and modify call of diagonal for links:

Resize the cluster layout based on number of child nodes

i am working in d3 ,rotating cluster layout ..i want to resize the cluster layout based on number of child nodes..
based on my code ,when i open the parent with minimum child ,there is no problem
when i open a parent that contains more child,there is some overlapping ,so want to reduce the cluster size further,when there is more number of child in the parent...how can i do this??
my entire code is

Circle Pack & Force layout on same page?

I am very new to d3 and svg, this may sound very naive.
I have one force layout graph and one Circle pack and want to show them both on one page side by side. I went to the "Multiple layouts on same page (multiple force layouts same page)" questions but not able to understand how can I put these layout in div element.

Note, some of the CSS was left out from one of the graphs. Adjust that as needed. The key to getting the d3 graph to load into a div is by this code below. Notice the # within the string name of the div id.
var svg = d3.select("#left-div").append("svg")
Instead of this code below.
var svg = d3.select("body").append("svg")
The next issue that I ran into was due to a duplicate var named "svg" between both scripts, so I renamed one of them to svg2.
