This interactive tree diagram maps programming paradigms, languages, and associated frameworks across four hierarchical levels. Built with React and D3.js v7, it renders an SVG visualization where nodes are positioned and connected by curved links. The chart displays the relationships from a root node representing programming languages, branching into categories like Object-Oriented and Functional, then to specific languages such as Java or Haskell, and finally to example frameworks. The code uses the D3 `stratify` function to convert flat parent-child data into a tree structure.
