Learn more on what and how to make an Sankey diagram. These hands-on samples of the diagrams are available in high resolution for you to print. Sankey diagrams are a specific type of flow diagram, in which the width of the arrows is shown proportionally to the flow quantity. Sankey diagrams put a visual emphasis on the major transfers or flows within a system. They are helpful in locating dominant contributions to an overall flow. Often, Sankey diagrams show conserved quantities within defined system boundaries.
Sankey diagrams are named after Captain Sankey, who created a diagram of steam engine efficiency that used arrows having widths proportional to heat loss. These diagrams summarize all the energy transfers taking place in a process. The thicker the line or arrow, the greater the amount of energy involved. Typically, Sankey diagrams are used to visually show the transfer of energy, money or materials, but they can be used to show the flow of any isolated system process. Sankey diagrams are often used in fields of science especially Physics. They are used to represent energy inputs, useful output and wasted output.

Sankey Diagrams display flows and their quantities in proportion to one another. The width of the arrows or lines are used to show their magnitudes, so the bigger the arrow, the larger the quantity of flow. Flow arrows or lines can combine together or split through their paths on each stage of a process. Color can be used to divide the diagram into different categories or to show the transition from one state of the process to another.
