This tree visualization displays a hierarchical taxonomy of programming languages organized by paradigms and use cases across three or more levels. Built with D3 v7 and React, the diagram uses d3.hierarchy and d3.tree layout with linkHorizontal paths to draw branching connections. Nodes are distinguished by depth: the root appears as a diamond, internal nodes as rounded rectangles, and leaves as circles, with color coding via d3.scaleOrdinal. Interactive labels identify each language while SVG rendering provides crisp output on a light background.
