D3.js Collapsible tree - Show more than only name of node

Question

I and using collapsible tree as shown in this link http://bl.ocks.org/mbostock/4339083 and I need to display details of each nodes. Here its only showing name. Any example or any link??

Just append new text elements for each additional information and adjust the dy positions to place them suitably. Also don't forget to use selectAll instead of select for updating fill-opacity of text elements during collapse/expand actions.

 var flare = { "name": "flare", "info1": "flare subtext 1", "info2": "flare subtext 2", "children": [ { "name": "analytics", "info1": "analytics subtext 1", "info2": "analytics subtext 2", "children": [ { "name": "cluster", "info1": "cluster subtext 1", "info2": "cluster subtext 2", "children": [ {"name": "AgglomerativeCluster", "size": 3938,"info1": "AgglomerativeCluster subtext 1","info2": "AgglomerativeCluster subtext 2"} ] }, { "name": "optimization", "info1": "optimization subtext 1", "info2": "optimization subtext 2", "children": [ {"name": "AspectRatioBanker", "size": 7074,"info1": "AspectRatioBanker subtext 1","info2": "AspectRatioBanker subtext 2"} ] } ] }, { "name": "animate", "info1": "animate subtext 1", "info2": "animate subtext 2", "children": [ {"name": "Easing", "size": 17010,"info1": "Easing subtext 1","info2": "Easing subtext 2"} ] } ] }; var margin = {top: 20, right: 120, bottom: 20, left: 120}, width = 960 - margin.right - margin.left, height = 800 - margin.top - margin.bottom; var i = 0, duration = 750, root; var tree = d3.layout.tree() .size([height, width]); var diagonal = d3.svg.diagonal() .projection(function(d) { return [dy, dx]; }); var svg = d3.select("body").append("svg") .attr("width", width + margin.right + margin.left) .attr("height", height + margin.top + margin.bottom) .append("g") .attr("transform", "translate(" + margin.left + "," + margin.top + ")"); root = flare; root.x0 = height / 2; root.y0 = 0; function collapse(d) { if (d.children) { d._children = d.children; d._children.forEach(collapse); d.children = null; } } root.children.forEach(collapse); update(root); d3.select(self.frameElement).style("height", "800px"); function update(source) { // Compute the new tree layout. var nodes = tree.nodes(root).reverse(), links = tree.links(nodes); // Normalize for fixed-depth. nodes.forEach(function(d) { dy = d.depth * 180; }); // Update the nodes… var node = svg.selectAll("g.node") .data(nodes, function(d) { return d.id || (d.id = ++i); }); // Enter any new nodes at the parent's previous position. var nodeEnter = node.enter().append("g") .attr("class", "node") .attr("transform", function(d) { return "translate(" + source.y0 + "," + source.x0 + ")"; }) .on("click", click); nodeEnter.append("circle") .attr("r", 1e-6) .style("fill", function(d) { return d._children ?
