This interactive tree diagram visualizes a hierarchical dataset, displaying nodes as colored boxes connected by labeled links with directional arrows. The layout renders synchronously in SVG and supports zooming and dragging via `d3.behavior.zoom`. Node colors map to `type` fields, and tooltips appear on hover, while link direction (SYNC or ASYN) is shown through arrow markers. Data loads from JSON using `d3.json`, and the layout uses `d3.layout.tree` with a `breadthFirstTraversal` to adjust SVG dimensions dynamically.
