Replicate pure JS version of D3 Zoomable Sunburst (observable)

I have been trying to replicate https://beta.observablehq.com/#mbostock/d3-zoomable-sunburst this in pure JS to use it in one of my projects. I am using PHP and Ajax to load Dynamic Data in JavaScript. I think the code in the Observable link is not in pure JS but rather Node or something else.
I am a newbie in Scripting, hence it is becoming very difficult for me to understand the written code. I do know that a pure JS will need the data (flare.json) in a specific format, which will generate the expected output. I can control the JSON structure from the backend, but I am unable to generate an output like the link.
I have followed multiple examples online:
https://bl.ocks.org/mbostock/4348373
And the same in d3 version 4 (which is very similar to v5, used in the Observable example):
https://bl.ocks.org/maybelinot/5552606564ef37b5de7e47ed2b7dc099
I have been trying to convert the Observable Zoomable Sunburst into JS functions, but I am unable to make it work. I have the exact same flare.json file and tried to recreate exact functions as therein Observable one. But it still is not working.
I am attaching my work. How can I get it working?
Sample Work
I have also tried to seek help on the Google Groups for d3-js, but I haven't got any help from there too.
The closest possible output which I have achieved till now is mentioned below:
var margin = {top: 288, right: 416, bottom: 288, left: 416},
radius = Math.min(margin.top, margin.right, margin.bottom, margin.left) - 5;
var hue = d3.scale.category10();
var luminance = d3.scale.sqrt()
.domain([0, 1e6])
.clamp(true)
.range([90, 20]);

.attr("width", margin.left + margin.right)
.attr("height", margin.top + margin.bottom)
.append("g")
.attr("transform", "translate(" + margin.left + "," + margin.top + ")");

d3 v4 donut chart has text and poylines that overlap with small values

I am trying to figure out how to arrange the labels so that they do not overlap. Here is a picture of the chart
As you can see, with really small values, the text labels overlap. I tried to iterate over each text element and modify it's position, but that doesn't seem to be working. You can see at the bottom of this function that I tried to get the position of each text element and then modify it. What am I doing wrong? I've been at it for hours.

}

I had the same issue. The best solution for me was to increase the size of the Svg area (based on current window) and add some padding to the legends based on the radius of the donut.
ie:
var margin = {top: 20, right: 100, bottom: 30, left: 40};
var svgWidth = window.innerWidth - (window.innerWidth/4);
var width = svgWidth,
height = (Math.min(width) / 2) + 100,
radius = Math.min(width, height) / 3;
var legendRectSize = (radius * 0.08);
var legendSpacing = (radius * 0.05);
This worked for me until the item count became too high. I amended from labels around the edge to display in the center, on slice/arc hover events. (There is an animation on the data value, which is why they are slanted in this snapshot)
I thought this made the unreadable data labels less confusing.

I thing you had same problem with this, you need to add more margin to your pie chart segment, assume your pie return 3% value, and you draw a text with line, it will stack on another, you need to devine margin if that value < 3 draw text with y+margin
if(percent<3){
o[1]
pos[1] += i*15
}
//return [label.centroid(d),[o[0],0[1]] , pos];
return [label.centroid(d),[o[0],pos[1]] , pos];
})
try to append this code structure to your chart

Updating D3 V3 Zoomable Sunburst data breaks chart

I'm new to programming D3, we are having a problem updating the sunburst chart without causing it to break its transitions. When the data is changed, parts of the chart stop resizing for the zooming feature and appear to be over each other. Additionally, I get errors resulting, apparently, from the interpolation of the flags each "arc" in the graph (i.e. Error: attribute d: Expected arc flag ('0' or '1'), "…125862517296 0 0.987032831999999…".). We are using a tween that is specific for this problem and thus can't understand what might be causing it.
Since I'm inexperienced in this language I've spent several days on this problem only to see it come back. If any of you could help I would appreciate it immensely.
Here's a working fiddle that I created to illustrate our problem:
- https://jsfiddle.net/v9ab0vms/1/
The problem can be seen by waiting 5 seconds and clicking the "Commercial" and then "Communications" arcs. Causing the transition errors and breaking some of the arcs. Zooming the graph while the data gets changed causes it to break in other ways, any help on that would also be greatly appreciated. I was just trying to fix it step by step.
Picture of broken chart arcs
The code has to be posted as well so I'm just inserting the two main functions for the sunburst:

Edit: To clarify:
This is in D3 V3.
We have two variables one with the full dataset

D3.js rotate shape without rotating text inside

I want to create rotate animation in a d3.js chart. With help of Gilsha I was able to create a chart like this :
Now on click of any of the outer circles i want to rotate all circles and align the one which was clicked in the place of "hllooo" circle.
I have copied one angletween which is rotating the circles but the problem is that text inside that circle also gets rotated and creates something like this:
As you can see the text is also rotated which i dont want. The code for transform function is:
function angleTween(d, i) {
var angle = 360 - ((i + 1) * 70);
var i = d3.interpolate(0, 90);
return function (t) {
return "rotate(" + i(t) + ")";
};
}
So how to keep text unrotated and just rotate the shape ?

Calulcate the x and y attributes of text elements by using SVGPoint matrixTransform.
earth.on('click', function() {
texts.style("opacity", 0);
earthLayer
.transition()
.duration(2000)
.attrTween("transform", angleTween)
.each("end", function() {
var svgEl = this.ownerSVGElement;
var angle = d3.select(this).attr("transform").match(/\d+/g)[0];
var matrix = svgEl.createSVGMatrix().rotate(angle);
texts.each(function(d, i) {
var point = this.ownerSVGElement.createSVGPoint();
point.x = +d.cx;
point.y = +d.cy;
point = point.matrixTransform(matrix);
d3.select(this).attr("x", point.x).attr("y", point.y);
});
texts.style("opacity", 1);
});
});

Javascript array filter | Custom method

I have a problem. Look at the picture below.
The data for my pie is:
var data = [{statusid:"Paid", price:10},
{statusid:"Not accepted", price:20},
{statusid:"Canceled", price:20},
{statusid:"Waiting", price:1},
{statusid:"Refunded", price:1},
{statusid:"Pending", price:1}];
Is it possible to solve this problem by sorting input data? How?
Thanks!
P.S: D3.js code below:
var data = [{statusid:"Paid", price:10}, {statusid:"Not accepted", price:20}, {statusid:"Canceled", price:20}, {statusid:"Waiting", price:1}, {statusid:"Refunded", price:1}, {statusid:"Pending", price:1}];
var sumprice = 0;
for (var i in data) {
sumprice += data[i].price;
}
