This interactive tree diagram visualizes a small hierarchical dataset about Intel chip categories, including microprocessors and microcontrollers. Built with React and D3.js, the SVG-based visualization uses animated transitions to reposition nodes and links when users click to expand or collapse branches. The code leverages D3's layout and diagonal projection APIs, with a color-coding function that assigns red to the root and blue to child generations, while CSS styles define node and link appearance.
