With this free web app you create a downloadable sankey map which is helpful for analyzing flows and location througputs of your supply chain.
(An imbalance between inbound and outbound volume at an intermediate node may indicate a data completeness issue.)

You can simply copy-paste from Excel file (tab separated). Or enter data semicolon separated. Do not copy-paste table headers, but data rows only.

  • NodeID is a free format identifier of the node, used to define flows between nodes (From_NodeID → To_NodeID).

  • Stage means process step in the flow. For example: supplier (stage 1) → warehouse (stage 2) → customers (stage 3). Nodes within the same stage appear below each other. The number of stages as such is not limited.

  • Color can be set as RGBA (red,green,blue,alpha).
    • Red, green, blue are numbers between 1 and 255. You can use this color picker to determine values →
    • Alpha is a number between 0.0 (fully transparent) and 1.0 (fully opaque).
    • By default, flows get the color of origin node. But you can override it by specifying a color at individual flow level.

  • Node positions and node heights are automatically calculated based on flow quantities (and positions also based on the sequence of your input). With Offset_X and Offset_Y you can adjust a node's X and Y position.
It is advised to express flow quantities as numbers without thousand and decimal separator (whole number).
