This visualization shows a branching tree diagram of computer-related terms in Arabic and English, organized into categories like hardware, software, CPU components, and related terminology. The tree uses collapsible nodes, allowing viewers to expand or collapse sub-branches by clicking. Rendered as an SVG with animation, the layout is built with `d3.layout.tree` and `d3.svg.diagonal` for the curved links. The data is defined as a static JavaScript object, and node positions update with a smooth transition on each interaction.
