This visualization shows the distribution of a music streaming subscription price among value-added tax, the platform, artists, and record labels using a vertical Sankey diagram. The flow starts with the subscription price at the top and branches downward, with the artist's share routed straight down and the other shares positioned to alternating sides. Built with D3 v7 and React, the implementation uses cubic Bézier curves to draw the flows and custom node positioning logic, while the ResizeObserver API handles responsive resizing of the SVG.
