Integrate JSON data into your JavaScript code using d3.js

Having trouble uploading a .json file to my personal website that is needed to be read by JavaScript code. The goal is to include the data from the .json file in the body of the website.

This is the code I am currently using to read and utilize the .json file:

d3.json("flare.json", function(error, flare) {
  if (error) throw error;

  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);
});

However, I am unsure of how to embed the json data into the script as required.

This is how the structure of my .json file looks like:

{
 "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}
     ]
    },
    {
     "name": "graph",
     "children": [
      {"name": "BetweennessCentrality", "size": 3534},
      {"name": "LinkDistance", "size": 5731},
      {"name": "MaxFlowMinCut", "size": 7840},
      {"name": "ShortestPaths", "size": 5914},
      {"name": "SpanningTree", "size": 3416}
     ]
    },
    {
     "name": "optimization",
     "children": [
      {"name": "AspectRatioBanker", "size": 7074}
     ]
    }
   ]
  },

Answer №1

You have the option to directly embed your JSON data into your JavaScript code, as JSON is essentially an object.

var treeData = {
 "name": "tree",
 "children": [
  {
   "name": "category1",
   "children": [
    {
     "name": "item1",
     "size": 100
    },
    {
     "name": "item2",
     "size": 200
    }
   ]
  },
  {
   "name": "category2",
   "children": [
    {
     "name": "item3",
     "size": 150
    },
    {
     "name": "item4",
     "size": 120
    }
   ]
  }
 ]
};


root = treeData;
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);
