What it is

SankeyMATIC is a browser-based tool for making Sankey diagrams. Each line describes a flow with a source, value, and target. The tool lays out proportional nodes and connections, with controls for labels, colors, dimensions, and layout.

Why it is selected

Budgets, conversion funnels, and energy flows can be difficult to explain in a table alone. SankeyMATIC turns editable text into a diagram, making it easy to compare the relative size of each flow without writing code first.

Who it suits

Analysts, designers, instructors, and content creators who need to present the movement of money, materials, users, or other quantities.

Useful for

  • Turning a budget allocation or conversion path into a proportional Sankey diagram
  • Adjusting diagram dimensions, labels, and colors for a presentation or article

Usage note

In this review, entering Research [3] Draft, Draft [2] Publish, and Draft [1] Revise produced four nodes and three flows, with total input and output both equal to 3. PNG and SVG export and public links were not tested. The official site says input data and image generation are processed locally in the browser. A public link may expose the data to anyone who has it, so it should not be used for sensitive information.
