Graph with Reflection on Code

This project demonstrates a simple graph data structure and its visualization using D3.js.
The graph supports adding nodes, directed edges, and reflexive edges (self‑loops).
The UI renders the graph in an SVG canvas with a force‑directed layout.

Features

• Pure JavaScript implementation (no Python or other languages).
• Reflexive edges can be added automatically.
• Interactive visualization with drag support.
• Simple test suite using Jest.
