Integrate a JSON file into d3.js using the d3.layout.partition function

I found this interesting resource at

Instead of the usual method using d3.json("flare.json", function(root) {

I'd like to know how to use the JSON data directly within the HTML file. For instance, if I have:

var json = [{
    "name": "flare",
    "children": [
        {"name": "analytics",
            "children": [
                {"name": "cluster","children": [{"name": "AgglomerativeCluster", "size": 3938},
                                                {"name": "CommunityStructure", "size": 3812},
                                                {"name": "HierarchicalCluster", "size": 6714},
                                                {"name": "MergeEdge", "size": 743}
                                                ]
                },

How can I implement this data structure in place of an external JSON file?

JSON File Link:

If possible, could someone provide a JSFiddle example for reference?

Thanks in advance.

Answer №1

There are two methods to accomplish this goal:

1. Start by assigning the JSON data to a variable, then proceed to create any desired layout.

2. Utilize a single function to retrieve the JSON data.

View Fiddle for the first solution

var root = json;

Fiddle for the second solution

var root = getData();
  var g = vis.selectAll("g")
      .data(partition.nodes(root))
    .enter().append("svg:g")
      .attr("transform", function(d) { return "translate(" + x(d.y) + "," + y(d.x) + ")"; })
      .on("click", click);
