Uncaught error reading in json data to d3 force-directed graph

I am having a similar problem to the one described here, but the solution offered there doesn't seem to work for me. I am trying to create a force-directed graph with force-based label placement using my own json data. I'm running into an unspecified uncaught javascript error at the point of reading in my data. My data is in the following format:
{"nodes": [{"name": Bob, "id": 1}, {"name": Suzy, "id": 2}],
"links": [{"source": 1, "target":2}]}
My script is below. Any insight would be enormously helpful!
<script type="text/javascript" charset="utf-8">
var w = 960, h = 500;
var labelDistance = 0;
var vis = d3.select("body").append("svg:svg").attr("width", w).attr("height", h);
var nodes = [];
var labelAnchors = [];
var labelAnchorLinks = [];
var links = [];
d3.json("data.json", function(error, graph) {
if (error) throw error;
for (var i = 0; i < graph.nodes.length; i++) {
var node = graph.nodes[i];
nodes.push(node);
labelAnchors.push({
node : node
});
labelAnchors.push({
node : node
});
}
graph.links.forEach(function(link, i) {
links.push({

});
labelAnchorLinks.push({

var force = d3.layout.force().size([w, h]).nodes(nodes).links(links).gravity(1).linkDistance(50).charge(-3000).linkStrength(function(x) {

force.start();
var force2 = d3.layout.force().nodes(labelAnchors).links(labelAnchorLinks).gravity(0).linkDistance(0).linkStrength(8).charge(-100).size([w, h]);
force2.start();
var link = vis.selectAll("line.link").data(links).enter().append("svg:line").attr("class", "link").style("stroke", "#CCC");

You can't read a file without specifying a correct path to your file system or to an external resource.
That means that you have to swap this line:
d3.json("/data/", function(error, graph) {
With something like:
d3.json("./data.json", function(error, graph) {
Or:
d3.json("http://www.somesite.com/data.json", function(error, graph) {
Also, make sure you are running a local server on your machine otherwise that call will fail.

D3 - Transition Arcs in Sunburst Chart

I have a sunburst chart made in D3. Each 'petal' represents a subset of data. When a user clicks on one of the 'petals', I would like it to transition, fanning out to only show that subset (see image):
I'm having trouble getting the code to properly transition.
On click, all 'petals' (besides the selected one) should disappear and the remain paths should animate along the circle (using attrTween, arcTween, and interpolate?). The primary value that would be changing is the angleSize (var angleSize = (2 * Math.PI) / theData.length;).
I've tried using this, this, this, and this as reference without much success. What's the best way to handle the animation?
Thanks for your time!

EDIT
Updated the code (based on this) to include a properly working enter, update, and exit pattern. Still unsure about the transition however. Most of the examples I've linked to use something similar to d3.interpolate(this._current, a);, tweening between differing data.
In this chart, this._current and a are the same, angleSize (var angleSize = (2 * Math.PI) / theData.length;), startAngle, and endAngle are the only thing that changes.

Your problem is that you are not really binding data to the elements, and therefore the transition is not possible. I mangled your code a little bit so the data contains all the nested information about the starting and ending angles, so that it can be bound to the paths inside each slice.
Take a look at this Plunker: https://plnkr.co/edit/a7cxRplzy66Pc1arM2a9?p=preview

As you can see, the key is correctly preparing the data (let's say the format in your example .tsv file is not the best choice, but sometimes we can't choose our data sources...)
Then afterwards, by putting the code for the paths generation inside the .each call on the slices, the data can be accessed from the function (d, i) { ... } callbacks and every element happens to receive the corresponding data.
Another trick is using the slices data (accessed inside the .each function via the dSlice and iSlice vars) on the paths' callbacks. This way the paths can consume this data for their own purposes. In this case, the company and study_name properties.
Now in order to tweak the transition and make it more accurate, the starting attributes can change. You can try by setting up some attributes for the paths in the .enter() phase.

Make D3 Graph Responsive to Windows Size

i am building a d3 Graph based on a json-File with an svg and groups:
Presentation.prototype.drawGraph = function() {
var _this;
this.margin = {
top: 0,
right: 0,
bottom: 0,
left: 0
};
this.width = 1000 - this.margin.left - this.margin.right;
this.height = 720 - this.margin.top - this.margin.bottom;
this.singleWidth = 50;
this.singleHeight = 32;
_this = this;
return d3.json("result.json", (function(_this) {
return function(err, json) {
if (err) {
console.error(err);
return;
}
// do something with the data
_this.x = d3.scale.ordinal().rangeBands([0, _this.width], 0, 0);
_this.y = d3.scale.linear().range([_this.height, 0]);
_this.svg = d3.select("#graph").append("svg").attr("width", _this.width + _this.margin.right + _this.margin.left).attr("height", _this.height + _this.margin.top + _this.margin.bottom).append("g").attr("transform", "translate(" + 0 + "," + 50 + ")");
_this.svg.append("rect").attr("x", -200).attr("y", -200).attr("width", 1200).attr("height", 1200).attr("fill", "#FFFFFF").on("click", function(data, index) {
_this.removeRenderedContent();
return _this.clickOnBackgroundRect();
});
_this.groups = _this.svg.selectAll("g").data(json).enter().append("g").attr("class", function(data, index) {return "group-case " + data.type;});
_this.groups.on("click", function(data, index) {
_this.removeRenderedContent();
_this.clickOnGroupCaseRect(data, index, this);
return false;
});
_this.groups.attr("transform", function(data, index) {
return "translate(" + data.x + "," + data.y + ")";
});
_this.groups.append("rect").attr("width", _this.widthFilter).attr("height", _this.heightFilter).attr("x", 0).attr("y", 0).attr("rx", 10).attr("ry", 10);
_this.groups.append("g").append("text").attr("y", 7).attr("x", 7).text(function(data) {return data.title;}).call(function(data, xpadding) {return _this.wrapGroup(data, xpadding);}, 7);
_this = _this;
return _this.groups.append("g").each(function(data, index) {
return _this.drawChildren(this, data, index);
});
};
})(this));
};
What i want to do is to make this graph responsive to the current browser-window size. Does anyone know the easiest way to do this?
Thanks in advance.

D3 Prevent Path Wrap

I'm building a map using D3 here: http://generationone.kera.org/map/
I'm hoping to find some way to prevent wrapping around the canvas (especially off the top) . I tried a couple different threads on here about translating the path and similar with little luck...

Bubble tree in d3?

Is there an equivalent implementation of a Bubble Tree in D3? In the link I provided, the Bubble Tree was implemented in RaphaelJS and jQuery.

The straight answer to your question is no.
Using the resources at https://github.com/okfn/bubbletree/tree/master/build, the information you already know, and the information provided on http://d3js.org/ and through D3's documentation on GitHub, you should be able to conjure up your own bubble tree for D3!
This is a piece of JavaScript I used a long time ago to visualize binary tree data:
var updateVisual;
updateVisual = function() {
var drawTree, out;
drawTree = function(out, node) {
var col, gray, i, line, lineElt, lines, sub, _results, _results1;
if (node.lines) {
out.appendChild(document.createElement("div")).innerHTML = "<b>leaf</b>: " + node.lines.length + " lines, " + Math.round(node.height) + " px";
lines = out.appendChild(document.createElement("div"));
lines.style.lineHeight = "6px";
lines.style.marginLeft = "10px";
i = 0;
_results = [];
while (i < node.lines.length) {
line = node.lines[i];
lineElt = lines.appendChild(document.createElement("div"));
lineElt.className = "lineblock";
gray = Math.min(line.text.length * 3, 230);
col = gray.toString(16);
if (col.length === 1) col = "0" + col;
lineElt.style.background = "#" + col + col + col;
console.log(line.height, line);
lineElt.style.width = Math.max(Math.round(line.height / 3), 1) + "px";
_results.push(i++);
}
return _results;
} else {
out.appendChild(document.createElement("div")).innerHTML = "<b>node</b>: " + node.size + " lines, " + Math.round(node.height) + " px";
sub = out.appendChild(document.createElement("div"));
sub.style.paddingLeft = "20px";
i = 0;
_results1 = [];
while (i < node.children.length) {
drawTree(sub, node.children[i]);
_results1.push(++i);
}
return _results1;
}
};
out = document.getElementById("btree-view");
out.innerHTML = "";
return drawTree(out, editor.getDoc());
};
Just insert some circular elements and manipulate it a bit to style in a circular manor and you should have a good program set!

Here you go. I didn't add the text or decorations, but it's the meat and potatoes:
function bubbleChart(config) {
var aspectRatio = 1,
margin = { top: 0, right: 0, bottom: 0, left: 0 },
radiusScale = d3.scale.sqrt(),
scan = function(f, data, a) {
a = a === undefined ? 0 : a;
var results = [a];
data.forEach(function(d, i) {
a = f(a, d);
results.push(a);
});
return results;
},
colorScale = d3.scale.category20(),
result = function(selection) {
selection.each(function(data) {
var outerWidth = $(this).width(),
outerHeight = outerWidth / aspectRatio,
width = outerWidth - margin.left - margin.right,
height = outerHeight - margin.top - margin.bottom,
smallestDimension = Math.min(width, height),
sum = data[1].reduce(function(a, d) {
return a + d[1];
}, 0),
radiusFractions = data[1].map(function(d) {
return Math.sqrt(d[1] / sum);
}),
radiusNormalSum = radiusFractions.reduce(function(a, d) {
return a + d;
}, 0),
scanned = scan(function(a, d) {
return a + d;
}, radiusFractions.map(function(d) {
return d / radiusNormalSum;
}), 0);
radiusScale.domain([0, sum]).range([0, smallestDimension / 6]);
var svg = d3.select(this).selectAll('svg').data([data]),
svgEnter = svg.enter().append('svg');
