This interactive mind map visualizes a hierarchical tree of topics related to Leonardo da Vinci, using data from a JSON file that includes nodes linking to Wikipedia articles. Built with D3.js (v3) and jQuery, it features a custom right-click context menu that appears at the cursor position, with menu items sized dynamically based on text measurement. The SVG-based tree includes collapsible nodes, tooltips, zoom and drag capabilities, and animated transitions, with node colors assigned by type.
