A multi-section Bitcoin dashboard visualizes market price, network hashrate, halving cycles, volatility, drawdown, and mining profitability. It animates across selectable time ranges and an electricity-price slider, with a trade diagnostic section showing per-trade P&L, sentiment outcomes, parallel coordinates, and a hand-drawn Sankey flow. Built with D3 v7, it uses SVG rendering, d3.scaleTime, d3.scaleLog, d3.brush, and JSON data files for prices, fear/greed, hashrate, and miner specifications.
