Sankey Diagram

Sankey diagrams visualize flows and transfers between nodes, where the width of each arrow is proportional to the quantity flowing through it. Originally developed to visualize energy transfer, they're now used for budget flows, customer journeys, material flows, and any process where tracking the magnitude of transfers is important. The conservation of flow (what goes in must come out) makes them excellent for identifying inefficiencies and major pathways.

"Create an interactive Sankey diagram showing 'US Energy Flow' from sources to end uses. Generate realistic data in quadrillion BTU: Sources (left): Coal (11), Natural Gas (32), Petroleum (35), Nuclear (8), Renewables (12). Transform through: Electricity Generation (38), Direct Use (60). End Uses (right): Residential (21), Commercial (18), Industrial (33), Transportation (26). Show energy losses in electricity generation as a separate flow to 'Rejected Energy' (24). Color flows by source type (Coal: gray, Gas: blue, Oil: brown, Nuclear: purple, Renewables: green). Add hover labels with flow values and percentages. Include a title with total energy consumption."
