This interactive D3.js visualization displays a hierarchical tree structure using rectangular nodes connected by curved links. Each node is color-coded by type (blue, green, yellow, purple) and contains labels, version numbers, and directional link descriptions. The tree expands and collapses on click, with tooltips showing additional details. Built with D3 v3 and jQuery, it uses the `d3.layout.tree` algorithm for positioning and SVG elements for rendering, with zoom and drag capabilities via `d3.behavior.zoom`.
