Dynamically update D3 Sunburst if the source json is updated (item added or deleted)

I am new to D3 and trying to dynamically update the chart if the source json is modified. But I am not able to achieve this.
Please check this plunkr
Js:
var width = 500,
height = 500,
radius = Math.min(width, height) / 2;
var x = d3.scale.linear()
.range([0, 2 * Math.PI]);
var y = d3.scale.sqrt()
.range([0, radius]);
var color = d3.scale.category10();
var svg = d3.select("body").append("svg")
.attr("width", width)
.attr("height", height)
.append("g")
.attr("transform", "translate(" + width / 2 + "," + (height / 2 + 10) + ") rotate(-90 0 0)");
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));
})
.outerRadius(function(d) {
return Math.max(0, y(d.y + d.dy));
});
//d3.json("/d/4063550/flare.json", function(error, root) {
var root = initItems;
var g = svg.selectAll("g")
.data(partition.nodes(root))
.enter().append("g");
var path = g.append("path")
.attr("d", arc)
.style("fill", function(d) {
return color((d.children ? d : d.parent).name);
})
.on("click", click)
.each(function(d) {
this.x0 = d.x;
this.dx0 = d.dx;
});
//.append("text")
var text = g.append("text")
.attr("x", function(d) {
return y(d.y);
})
.attr("dx", "6") // margin
.attr("dy", ".35em") // vertical-align
.attr("transform", function(d) {
return "rotate(" + computeTextRotation(d) + ")";
})
.text(function(d) {
return d.name;
})
.style("fill", "white");
function computeTextRotation(d) {
var angle = x(d.x + d.dx / 2) - Math.PI / 2;
return angle / Math.PI * 180;
}
function click(d) {
console.log(d)
// fade out all text elements
if (d.size !== undefined) {
d.size += 100;
};
text.transition().attr("opacity", 0);
path.transition()
.duration(750)
.attrTween("d", arcTween(d))
.each("end", function(e, i) {
// check if the animated element's data e lies within the visible angle span given in d
if (e.x >= d.x && e.x < (d.x + d.dx)) {
// get a selection of the associated text element
var arcText = d3.select(this.parentNode).select("text");
// fade in the text element and recalculate positions
arcText.transition().duration(750)
.attr("opacity", 1)
.attr("transform", function() {
return "rotate(" + computeTextRotation(e) + ")"
})
.attr("x", function(d) {
return y(d.y);
});
}
});
} //});
// Word wrap!
var insertLinebreaks = function(t, d, width) {
alert(0)
var el = d3.select(t);
var p = d3.select(t.parentNode);
p.append("g")
.attr("x", function(d) {

.attr('x', -width / 2)
.attr("width", width)
.attr("height", 200)
.append("xhtml:p")
.attr('style', 'word-wrap: break-word; text-align:center;')
.html(d.name);

alert(2)
};
//g.selectAll("text")
// .each(function(d,i){ insertLinebreaks(this, d, 50 ); });
d3.select(self.frameElement).style("height", height + "px");
// Interpolate the scales!
function arcTween(d) {
var xd = d3.interpolate(x.domain(), [d.x, d.x + d.dx]),
yd = d3.interpolate(y.domain(), [d.y, 1]),
yr = d3.interpolate(y.range(), [d.y ? 20 : 0, radius]);
return function(d, i) {
return i ? function(t) {
return arc(d);
} : function(t) {
x.domain(xd(t));
y.domain(yd(t)).range(yr(t));
return arc(d);
};
};
}
function arcTweenUpdate(a) {
console.log(path);
var _self = this;
var i = d3.interpolate({ x: this.x0, dx: this.dx0 }, a);
return function(t) {
var b = i(t);
console.log(window);
_self.x0 = b.x;
_self.dx0 = b.dx;
return arc(b);
};
}
setTimeout(function() {
path.data(partition.nodes(newItems))
.transition()
.duration(750)
.attrTween("d", arcTweenUpdate)
}, 2000);

In addition to what #Cyril has suggested about removing the following line:
d3.select(self.frameElement).style("height", height + "px");
I made further modifications in your fiddle: working fiddle
The idea used here is to add a function updateChart which takes the items and then generate the chart:
var updateChart = function (items) {
// code to update the chart with new items
}
updateChart(initItems);
setTimeout(function () { updateChart(newItems); }, 2000);
This doesn't use the arcTweenUpdate function you have created but I will try to explain the underlying concept:
First, you will need to JOIN the new data with your existing data:
// DATA JOIN - Join new data with old elements, if any.
var gs = svg.selectAll("g").data(partition.nodes(root));
then, ENTER to create new elements if required:
// ENTER
var g = gs.enter().append("g").on("click", click);
But, we also need to UPDATE the existing/new path and text nodes with new data:
// UPDATE
var path = g.append("path");
gs.select('path')
.style("fill", function(d) {
return color((d.children ? d : d.parent).name);
})
//.on("click", click)
.each(function(d) {
this.x0 = d.x;
this.dx0 = d.dx;
})
.transition().duration(500)
.attr("d", arc);
var text = g.append("text");
gs.select('text')
.attr("x", function(d) {
return y(d.y);
})
.attr("dx", "6") // margin
.attr("dy", ".35em") // vertical-align
.attr("transform", function(d) {
return "rotate(" + computeTextRotation(d) + ")";
})
.text(function(d) {
return d.name;
})
.style("fill", "white");
and, after everything is created/updated remove the g nodes which are not being used i.e. EXIT:
// EXIT - Remove old elements as needed.
gs.exit().transition().duration(500).style("fill-opacity", 1e-6).remove();
This whole pattern of JOIN + ENTER + UPDATE + EXIT is demonstrated in following articles by Mike Bostock:
General Update Pattern - I
General Update Pattern - II
General Update Pattern - III

In side the fiddle the setTimeout is not running because:
d3.select(self.frameElement).style("height", height + "px");
You will get Uncaught SecurityError: Failed to read the 'frame' property from 'Window': Blocked a frame with origin "https://fiddle.jshell.net" from accessing a frame with origin and the setTimeout never gets called.
So you can remove this line d3.select(self.frameElement).style("height", height + "px"); just for the fiddle.
Apart from that:
Your timeout function should look like this:
setTimeout(function() {
//remove the old graph
svg.selectAll("*").remove();
root = newItems;
g = svg.selectAll("g")
.data(partition.nodes(newItems))
.enter().append("g");
/make path
path = g.append("path")
.attr("d", arc)
.style("fill", function(d) {
return color((d.children ? d : d.parent).name);
})
.on("click", click)
.each(function(d) {
this.x0 = d.x;
this.dx0 = d.dx;
});
//make text
text = g.append("text")
.attr("x", function(d) {
return y(d.y);
})
.attr("dx", "6") // margin
.attr("dy", ".35em") // vertical-align
.attr("transform", function(d) {
return "rotate(" + computeTextRotation(d) + ")";
})
.text(function(d) {
return d.name;
})
.style("fill", "white");
}
working fiddle here

for the enter() and transitions to work you need to give d3 a way to identify each item in your data. the .data() function has a second parameter that lets you return something to use as an id. enter() will use the id to decide whether the object is new.
try changing
path.data(partition.nodes(newItems))
.data(partition.nodes(root));
to
path.data(partition.nodes(newItems), function(d){return d.name});
.data(partition.nodes(root), function(d){return d.name});

I need to create D3 chart as in the following link:
D3 bubble chart (Data displayed as Overall and by Sector)
Below are the screenshots of charts:
Overall View:
Sector view:
I have searched a lot, but not able to find any codebase or example for the same. So, i'm not sure of How i can achieve the same.
Please share the code/pointers to achieve the same chart using D3.
Thanks in advance,

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

add circle in a spiral chart with d3js with line connecting to center

hi I created a spiral chart in d3.js, and I want to add circle to different position of the spiral lines.according to there values.
circle closes to the center will have highest priority.
any idea how to do that.
here is the code which i wrote
var width = 400,
height = 430
num_axes = 8,
tick_axis = 1,
start = 0
end = 4;
var theta = function(r) {
return -2*Math.PI*r;
};
var arc = d3.svg.arc()
.startAngle(0)
.endAngle(2*Math.PI);
var radius = d3.scale.linear()
.domain([start, end])
.range([0, d3.min([width,height])/2-20]);
var angle = d3.scale.linear()
.domain([0,num_axes])
.range([0,360])
var svg = d3.select("#chart").append("svg")
.attr("width", width)
.attr("height", height)
.append("g")
.attr("transform", "translate(" + width/2 + "," + (height/2+8) +")");
var pieces = d3.range(start, end+0.001, (end-start)/1000);
var spiral = d3.svg.line.radial()
.interpolate("cardinal")
.angle(theta)
.radius(radius);
//svg.append("text")
// .text("And there was much rejoicing!")
// .attr("class", "title")
// .attr("x", 0)
// .attr("y", -height/2+16)
// .attr("text-anchor", "middle")
//svg.selectAll("circle.tick")
// .data(d3.range(end,start,(start-end)/4))
// .enter().append("circle")
// .attr("class", "tick")
// .attr("cx", 0)
// .attr("cy", 0)
// .attr("r", function(d) { return radius(d); })
svg.selectAll(".axis")
.data(d3.range(num_axes))
.enter().append("g")
.attr("class", "axis")
.attr("transform", function(d) { return "rotate(" + -angle(d) + ")"; })
.call(radial_tick)
.append("text")
.attr("y", radius(end)+13)
.text(function(d) { return angle(d) + "°"; })
.attr("text-anchor", "middle")
.attr("transform", function(d) { return "rotate(" + -90 + ")" })
svg.selectAll(".spiral")
.data([pieces])
.enter().append("path")
.attr("class", "spiral")
.attr("d", spiral)
.attr("transform", function(d) { return "rotate(" + 90 + ")" });
function radial_tick(selection) {
selection.each(function(axis_num) {
d3.svg.axis()
.scale(radius)
.ticks(5)
.tickValues( axis_num == tick_axis ? null : [])
.orient("bottom")(d3.select(this))
d3.select(this)
.selectAll("text")
.attr("text-anchor", "bottom")
.attr("transform", "rotate(" + angle(axis_num) + ")")

Displaying total value for each item in a chord chart

I was working on the chord diagram and I am unable to show the total value for each product. I want it to display the total count for each category when I hover over the radial arc for a particular category. The example is taken from http://bl.ocks.org/mbostock/4062006. Any prompt help would be greatly appreciated. Thank you :)
