This tree chart visualizes a family classification hierarchy, showing generational relationships from Muni Naidu down to descendants like Samrat Chowdary and Alekya Chowdary. The code uses D3.js version 3.5.17 with `d3.layout.tree()` and `d3.svg.diagonal()` to render curved links and nodes as SVG elements. Node stroke colors come from the `type` property (e.g., orange, purple), while `level` drives fill colors (e.g., blue, green, pink, violet). A 750-millisecond transition animation expands the tree on load, with a pink background and custom CSS styling for interactive cursor pointers.
