The thicker the line or arrow, the greater the amount of energy involved. Figure 3. You can also interact with it either by clicking the link or the flow itself and leverage the cross highlighting/filtering feature of Power BI to get even more interesting insights in related data. In every step the losses are shown as an arrow branching out to the bottom, labeled with percentages (mass-%). One could call this the "efficiency" of food production, processing and consumption. It can happen with several data structure: evolution: the nodes are duplicated in 2 or more groups that represent stages. Step 1: Create a Tidy data frame. thanks to the Besides the energy actually used for motion at the wheel ("mechanische Energie") a large part of the energy is lost, especially as heat losses. Thus it shows not only flow values but also information about the structure and distribution of the defined system. learn how to customize your Sankey Diagram.

(Source: Prof. Mario Schmidt, INEC, Pforzheim University). It’s easy to say ‘Go with the flow’ but first you must know where the flow goes. In this case the custom visual displays links between source and destination with same links weights. The second element of a Sankey diagram is the links (or edges), that connect the nodes together. It’s easy to say ‘Go with the flow’ but first you must know where the flow goes. Sankey diagrams are diagrams representing flows between different nodes by using arrows whose width scales according to the value of the flow.. Two of the most famous Sankey diagrams (named after Irish captain Sankey) are Sankey's steam engine efficiency diagram and Minard's map of the French losses during the 1812 Russian campaign.
