Fork of ANY JSON tree (DRAFT)
This example shows any JSON object as a selectable, zoomable tree diagram using D3’s hierarchical layout. A custom `hierarchify` function converts arbitrary JSON data into the nested `{ name, children }` structure expected by `d3.hierarchy`, with node labels indicating each value’s type and content. The tree is rendered as SVG, with curved links via `d3.linkHorizontal` and pan/zoom through `d3.zoom`. It visualizes a sample dataset containing error and response fields, including nested arrays and objects. The interface supports interactive exploration of the JSON structure.
AI-generated descriptionAim: Display ANY JSON as a selectable tree.
The idea is to be able to use d3 as a JSON-explorer / picker.
Version 1.0 using the code from World Countries Tree from Curran

Probably the d3.tree is what we want to use ...
1. Restructure the data into hierarchical JSON format
The JSON format expected by a d3 tree
See function hierarchify in

Alternative ideas:
- See Stack exchange D3 JSON data conversion
var input = [
{ "dep": "d1", "name": "name1", "size": "size1" },
{ "dep": "d1", "name": "name2", "size": "size2" },
{ "dep": "d2", "name": "name1", "size": "size3" },
{ "dep": "d2", "name": "name1", "size": "size4" }
];
var output = {
"name": "root",
"children": d3.groups(input, d => d.dep).map(([k, vs]) => ({ "name": k, "children": vs }))
};
2. Present the hierarchical JSON as a tree
- See d3 | JSON data to tree layout
- or many others
3. Make the hierarchie interactive
…
4. Clicking a node should return the JSONPath to that node.
