This example shows an interactive, animated tree diagram of computer-related terms, including hardware, software, CPU components, and Arabic-labeled network concepts. The visualization uses D3.js version 3.5 to create and update hierarchical nodes, with click handlers to expand or collapse branches. SVG circles and text represent each node, while diagonal links connect parent and child elements. The layout uses `d3.layout.tree` and fixed-depth spacing, with transitions animating nodes from their parent’s previous position over 750 milliseconds. The data is embedded directly in the code as a JavaScript array.
