I am trying to implement paging in d3 tree. Can anyone please help me with the same.
Please find below my code with screenshots of current and expected output.
The data_tree is the input data variable. This gets read by script below and produces hierarchy tree as showed in screenshot
data_tree = {

I am using the Zoomable CirclePacking layout provided by d3.js. Each of my circles(at all levels) is uniquely identifiable.
I need to write a generic function that can draw svg arrows(with a text label) from any circle at any level to any other circle. How do I go about doing this?
Here is an example code snippet which connects nodes inside each circle with its parent circle on click.
var svg = d3.select("svg"),
margin = 20,
diameter = +svg.attr("width"),
g = svg.append("g").attr("transform", "translate(" + diameter / 2 + "," + diameter / 2 + ")");
svg.append('svg:defs').append('svg:marker')
.attr('id', 'head')
.attr('orient', 'auto')
.attr('markerWidth', '2')
.attr('markerHeight', '4')
.attr('refX', '0.1')
.attr('refY', '2')
.append('marker:polygon').attr('points', '0,0 0,4 2,2').attr('fill', 'red');
var color = d3.scaleLinear()
.domain([-1, 5])
.range(["hsl(152,80%,80%)", "hsl(228,30%,40%)"])
.interpolate(d3.interpolateHcl);
var pack = d3.pack()
.size([diameter - margin, diameter - margin])
.padding(2);

and the other nodes will disappear or gets dull.

is there any way of applying this kind of functionality in d3js?
There are several ways to make it. This is one of them:
circle.on("click", function(d) {
var thisNode = d.id
var connected = data.links.filter(function(e) {
return e.source === thisNode || e.target === thisNode
});
circle.attr("opacity", function(d) {
return (connected.map(d => d.source).indexOf(d.id) > -1 || connected.map(d => d.target).indexOf(d.id) > -1) ? 1 : 0.1
});
path.attr("opacity", function(d) {
return (d.source.id == thisNode || d.target.id == thisNode) ? 1 : 0.1
});
Check the demo with your code:
var color = d3.scale.category20();
//try{
// var data = JSON.parse(text);
//} catch (e) {
// window.alert("sometext: "+e);
//}
var data = {

I am trying to expand this force layout example by changing a nodes' shape from circle to rectangle when it is clicked. So I don't want to change any data but just want to replace the corresponding SVG element.
One of my approaches looked like this:
node.on("click", function() {
this.remove();
svg.selectAll(".node").data(graph.nodes).enter().append("rect")
.attr("class", "node")
.attr("width", 5).attr("height", 5)
.style("fill", function(d) { return color(d.group); });
});
So I removed the SVG element from the DOM and rebound the data, adding a rectangle for the now missing node.
Unfortunately this does not work (the force layout does not set any properties on the new element) and I have no idea if this a reasonable approach at all.
Any ideas how to do this properly?
Try this way.
node.on("click", function(d) {
var size = d.weight * 2 + 12;
d3.select(this).select("circle").remove();
d3.select(this).append("rect")
.attr("x", -(size / 2))
.attr("y", -(size / 2))
.attr("height", size)
.attr("width", size)
.style("fill", function(d) {
return color(1 / d.rating);
});
});

You've updated the dom elements, but not the array used by the force layout algorithm, so do this as the last line in the on click function:
graph.nodes = svg.selectAll(".node");
(You might also find without a data key function that random nodes get changed to rectangles rather than the one you clicked)
I have this D3 instance. I'm trying nodes to collapse and hide its childrens when click but I'm getting "Uncaught NotFoundError: Failed to execute 'insertBefore' on 'Node': The node before which the new node is to be inserted is not a child of this node." when I click one.
Since the error happens on d3.js I'm having a big trouble debugging it.
Here's the code
window.onload=function(){
var width = $(window).width();
height = $(window).height();
var force = d3.layout.force()
.gravity(.2)
.charge(-500)
.size([width, height])
.linkDistance(250);
var svg = d3.select("body").append("svg:svg")
.attr("width", width)
.attr("height", height);
var root = getData();
var nodes = flatten(root),
links = d3.layout.tree().links(nodes);
nodes.forEach(function(d, i) {
d.x = width/2 + i;
d.y = height/2 + 100 * d.depth;
});
root.fixed = true;
root.x = width / 2;
root.y = height / 2;
force.nodes(nodes)
.links(links)
.start();
var link = svg.selectAll("line")
.data(links)
