Cannot rotate text d3js - javascript

I'm trying to add text to the partition-sunburst example. I have followed a hint given on Google Group and I was able to add the text. Now I want to rotate it. The new angles seem to be correct, but all the text get gathered in one point.
This is the piece of code where I add and rotate the text:
var text = vis.data([json]).selectAll("text")
.data(partition.nodes)
.enter().append("svg:text")
.attr("x", function(d) { return radius * Math.cos(d.x + d.dx/2); } )
.attr("y", function(d) { return radius * Math.sin(d.x + d.dx/2); } )
.attr("dy", ".31em")
.style("font-size", "5px")
.attr("transform", function(d) {
var angle = (2 * Math.PI - d.x) * (180/Math.PI);
var rotation = "rotate(" + angle + ")";
console.log(rotation);
console.log("d.x=" + d.x + ", d.y=" + d.y);
return rotation;
})
.text(function(d) { return d.name; });
This is an image of what I get:
and this is the full script:
var width = 1000,
height = 1000,
radius = 350,
x = d3.scale.linear().range([0, 2 * Math.PI]),
y = d3.scale.pow().exponent(1.3).domain([0, 1]).range([0, radius]),
padding = 5,
color = d3.scale.category20c();
var vis = d3.select("#chart").append("svg")
.attr("width", width)
.attr("height", height)
.append("g")
.attr("transform", "translate(" + width / 2 + "," + height / 2 + ")");
var partition = d3.layout.partition()
.sort(null)
.size([2 * Math.PI, radius * radius])
.value(function(d) { return 1; });
var arc = d3.svg.arc()
.startAngle(function(d) { return d.x; })
.endAngle(function(d) { return d.x + d.dx; })
.innerRadius(function(d) { return Math.sqrt(d.y); })
.outerRadius(function(d) { return Math.sqrt(d.y + d.dy); });
d3.json("fracking.json", function(json) {
var path = vis.data([json]).selectAll("path")
.data(partition.nodes)
.enter().append("svg:path")
.attr("display", function(d) { return d.depth ? null : "none"; })
// hide inner ring
.attr("d", arc)
.attr("fill-rule", "evenodd")
.style("stroke", "#fff")
.style("fill", function(d) { return color((d.children ? d : d.parent).name); })
.each(stash);
var text = vis.data([json]).selectAll("text")
.data(partition.nodes)
.enter().append("svg:text")
.attr("x", function(d) { return radius * Math.cos(d.x + d.dx/2); } )
.attr("y", function(d) { return radius * Math.sin(d.x + d.dx/2); } )
.attr("dy", ".31em")
.style("font-size", "5px")
.attr("transform", function(d) {
var angle = (2 * Math.PI - d.x) * (180/Math.PI);
var rotation = "rotate(" + angle + ")";
console.log(rotation);
console.log("d.x=" + d.x + ", d.y=" + d.y);
return rotation;
})
.text(function(d) { return d.name; });
d3.select("#size").on("click", function() {
path
.data(partition.value(function(d) { return d.size; }))
.transition()
.duration(1500)
.attrTween("d", arcTween);
d3.select("#size").classed("active", true);
d3.select("#count").classed("active", false);
});
d3.select("#count").on("click", function() {
path
.data(partition.value(function(d) { return 1; }))
.transition()
.duration(1500)
.attrTween("d", arcTween);
d3.select("#size").classed("active", false);
d3.select("#count").classed("active", true);
});
});
// Stash the old values for transition.
function stash(d) {
d.x0 = d.x;
d.dx0 = d.dx;
}
// Interpolate the arcs in data space.
function arcTween(a) {
var i = d3.interpolate({x: a.x0, dx: a.dx0}, a);
return function(t) {
var b = i(t);
a.x0 = b.x;
a.dx0 = b.dx;
return arc(b);
};
}


I think you need to specify the center of rotation. Try this:
var text = vis.data([json]).selectAll("text")
.data(partition.nodes)
.enter().append("svg:text")
.attr("x", function(d) { return radius * Math.cos(d.x + d.dx/2); } )
.attr("y", function(d) { return radius * Math.sin(d.x + d.dx/2); } )
.attr("dy", ".31em")
.style("font-size", "5px")
.attr("transform", function(d) {
var angle = (2 * Math.PI - d.x) * (180/Math.PI);
var rotation = "rotate(" + angle + "," + d3.select(this).attr("x") + "," d3.select(this).attr("y") +")";
console.log(rotation);
console.log("d.x=" + d.x + ", d.y=" + d.y);
return rotation;
})
.text(function(d) { return d.name; });

Horizontally Flipping Text Halfway Around a Circle with D3.js

I am making a Sunburst chart and am almost complete, but I want the text to flip half-way around the circle to make it easier to read. Using help from another question here on stackoverflow I have been able to get the text to flip, but it drops down a level. I have tried modifying the computeTextRotation function to account for this, but to no prevail. I am curious if anyone is able to help me solve this problem.
Here is a picture of the chart:
Here is the computeTextRotation functions code:
function computeTextRotation(d) {
var rotation = (d.x + d.dx / 2) * 180 / Math.PI - 90;
return {
global: rotation,
correction: rotation > 90 ? 180 : 0
};
}
...
.attr("transform", function(d)
{
var r = computeTextRotation(d);
return "rotate(" + r.global + ")"
+ "translate(" + radius / 3. * d.depth + ")"
+ "rotate(" + -r.correction + ")";
}
)
Here is the entire JavaScript code:
var margin = {top: 500, right: 500, bottom: 500, left: 500},
radius = Math.min(margin.top, margin.right, margin.bottom, margin.left) - 150;
function filter_min_arc_size_text(d, i) {return (d.dx*d.depth*radius/1)>14};
var hue = d3.scale.category10();
var luminance = d3.scale.sqrt()
.domain([0, 1e6])
.clamp(true)
.range([90, 20]);
var svg = d3.select("body").append("svg")
.attr("width", margin.left + margin.right)
.attr("height", margin.top + margin.bottom)
.append("g")
.attr("transform", "translate(" + margin.left + "," + margin.top + ")");
var partition = d3.layout.partition()
.sort(function(a, b) { return d3.ascending(a.name, b.name); })
.size([2 * Math.PI, radius]);
var arc = d3.svg.arc()

Your corrective factor rotates the text 180 degrees, this is only half of what you need:
By rotating 180 degrees, you get text that is right way up, but now that moves in the opposite direction because the direction of the text is also rotated.
For the second half of the circle, you need to specify a text-anchor of "end" so that the text is anchored where it should be. Currently it is anchored where it starts, which is fine for the first half of the circle.
When styling the text you'll need to perform a check to see if the text anchor needs to be set to "end" as opposed to "start":
text.style("text-anchor",function(d) { return isRotated(d) ? "end" : "start" })
With the check looking something like:
function isRotated(d) {
var rotation = (d.x + d.dx / 2) * 180 / Math.PI - 90;
return rotation > 90 ? true : false
}
The margins also need to be adjusted:
.attr("dx", function(d) {return isRotated(d) ? "-6" : "6"}) //margin

D3: Rotating labels in Bi-Level Partition

I'm using D3 and javascript to create a BiLevel Partition following this example. The labels in the left side of the diagram are upside down, and I was trying to rotate them, but I've not been successful yet.
I found numerous cases of people with the same problem, but using Sunburst. Also tried to implement those solutions, but I'm still unable to solve this problem.

D3JS Sunburst not updating text

I'm trying to display a sunburst with text. I used the code from a sunburst example and tried to add text to it (worked), but when it updates, my text disappears. I can only get it to display all text or text when loaded then no text. So when it updates, the text is either gone or is not in sync with the data.
Can anybody tell me what is wrong because I don't know anymore.

Update: You can find my code on https://github.com/KenBonny/D3-Chart-Test
You can view the handywork on github page: https://kenbonny.github.io/D3-Chart-Test/

It's because you are not passing any data to click
wirte function click() { instead of function click(data) {
and I think it will work

I am learning d3.js, so I don't know how to do it. Please help me.

Doing this ends up being a bit code heavy, but for my graphs I tend to have 3 different parts: setup, draw and redraw. In setup I set up all the SVG containers and bind the data. In draw, I do the initial data draw (this tends to have different animations, fade-ins, etc). Then I bind window.onresize to the redraw all of the SVG data based on window/container dimensions.
I can provide you with an example of my code if you would like.

D3 "Sunburst" Center Path Size

So I've got a pretty standard D3 "Sunburst" diagram. However, the center path (i.e. the root), is too big. It's taking up a large portion of my diagram that is being wasted as the more important arcs around it struggle for space.
I'm about to add labels to the outer rings but I need more space.
See below.
I want to make the center circle (the light grey bit) smaller and the outer rings thicker.
Can any one help me?
Here's my code:

var y = d3.scale.sqrt()

.attr("width", width)
.attr("height", height)

.attr("id", "scan")

var partition = d3.layout.partition()
.value(function(d) { return d.size; });
var arc = d3.svg.arc()
.startAngle(function(d) { return Math.max(0, Math.min(2 * Math.PI, x(d.x))); })
.endAngle(function(d) { return Math.max(0, Math.min(2 * Math.PI, x(d.x + d.dx))); })
.innerRadius(function(d) { return Math.max(0, y(d.y)); })

The non-linear response in ring width is due to the square root in the y scale, in this line:
var y = d3.scale.sqrt()
.range([0, radius]);
If you want a linear reponse just change the scale to linear as in:
var y = d3.scale.linear()
.range([0, radius]);
You should then see evenly spaced rings.
