I am interested in creating a tree structure similar to the one shown in this example: http://bl.ocks.org/1062288. My goal is to start with all nodes collapsed, resulting in only the root node being displayed in the initial graph.

Choice 1: Adjust the JSON
To make a change, simply modify the JSON file named readme.json, replacing instances of children with _children.
Choice 2: Revise the JavaScript Code
Make adjustments to the JavaScript code so that the attributes children and _children are interchanged for each node. This revision can be implemented using the following snippet:
var nodes = flatten(root);
nodes.forEach(function(d) {
d._children = d.children;
d.children = null;
});
For a demonstration of the second option, you can access this JSFiddle.
const nodeList = getFlattenedNodes(root);
for (let j=0;j<nodeList.length;j++){toggle(nodeList[j])}
If you're searching, here are two simple lines of code that are concise and straightforward.
Here is some code for future reference:
d3.json("json/results.json", function(data) {
treeData = data;
treeData.x0 = height / 2;
treeData.y0 = 0;
function expandAll(node) {
if (node.children) {
node.children.forEach(expandAll);
expand(node);
}
}
treeData.children.forEach(expandAll);
expand(treeData);
updateTree(treeData);
});
