This interactive visualization displays a hierarchical tree with collapsible nodes, where each node is rendered as a colored box representing different data types. The tree supports zooming and panning through mouse interactions, with tooltips appearing when hovering over nodes. Built with D3.js v3 and jQuery, it uses the `d3.layout.tree` algorithm to position nodes and SVG for rendering, with animated transitions on node expansion and collapse. The example loads hierarchical JSON data containing nested objects with properties such as node name, type, and version, and color-codes nodes based on their type values.
