This interactive mind map visualizes Leonardo da Vinci’s biography and related topics using a hierarchical tree layout rendered as SVG with D3.js v3. Users can pan, zoom, and click nodes to expand or collapse branches, while a custom HTML context menu appears on right-click with options like Share, Rename, and Delete. The visualization uses the `d3.layout.tree` API for positioning, with data loaded from a JSON file containing node names, types, and Wikipedia links. It includes smooth animations and a drop-shadow effect, with the tree structure dynamically sized based on the deepest node depth.
