This example presents a pseudo-Sankey diagram of a Bitcoin transaction, visualizing the flow of sats from multiple inputs to outputs, including a fee. The diagram uses static SVG paths and rectangles with linear gradients, bundled in a single HTML file and styled with CSS. D3.js v5 is loaded for potential data manipulation, though the visualization itself is manually defined in markup. The chart labels each side with values and includes a link to the transaction on blockchain.com.
