A Sankey diagram visualizes the magnitude of flow between connected nodes, making it ideal for tracing how quantities move through a system. Flow widths are proportional to the values they represent, so dominant pathways stand out immediately.
This sample traces energy from its sources through transformation stages to final end uses, measured in terawatt-hours per year. Custom HTML tooltips display income, outcome, and dropoff at each node, while conflict detection flags imbalances in the data. Lightened flow colors and positioned labels keep the complex multi-stage layout readable.
