Agatizer Copy-Trading Dashboard

Real-time dashboard for a copy-trading platform, fed by WebSocket data

Built the dashboard for a platform where users mirror other traders' positions. Rendered live WebSocket data with D3.js, and used virtual scrolling and RxJS streams to keep the interface responsive.
