This interactive visualization displays a hierarchical tree structure as collapsible boxes, with each node representing a named entity and its connections labeled with synchronization details (SYNC or ASYN). Built with D3.js v3 and jQuery, the tree uses SVG rendering and animated transitions for expand/collapse interactions. The code implements custom layout calculations, including collision detection to prevent node overlap, and enhances usability with zoom and drag capabilities via `d3.behavior.zoom`, while tooltips provide additional node information. Data is loaded from a JSON file defining the tree structure and node attributes like type and version.
