Sankey Energy Chart
Sankey Diagram is a type of flow diagram that depicts the flow of resources (material, energy, cost, etc.) from one node to another. The start and endpoints of each flow are called nodes and the flow paths between them are called links. There can only be one link between a pair of nodes. The value of the flow between each pair of nodes is encoded by the width of the link. The coloration of the links help establishes visual mapping with their respective nodes.
