Live Bitcoin Price Chart — Minimal Single-File HTML with Binance WebSocket
Create a single HTML file that displays a live, auto-updating Bitcoin (BTC/USDT) price chart. Requirements: - **Single file**: All HTML, CSS, and JavaScript in one file (CDN links are fine) - **Data source**: Binance WebSocket API (`wss://stream.binance.com:9443/ws/btcusdt@trade`) for real-time price data - **Charting**: Use Chart.js (or similar lightweight library via CDN) to render a clean line chart - **Live updates**: Chart should update in real-time as new trades come in (throttle updates to ~1 per second to keep it smooth) - **Minimal design**: Dark theme, clean typography, show current price prominently above the chart - **Time window**: Display the last 5 minutes of price data, with old points rolling off - **Responsive**: Should look good on both desktop and mobile - Keep it simple, elegant, and under 200 lines if possible
