Sankey Flow Show

Sankey Flow Show is a web application for drawing flow diagrams and Sankey diagrams in a browser. It is aimed at making these diagrams quickly, with the page describing them as attractive flow diagrams made in minutes. The service also names several diagram classes it can work with, including workflow diagrams, BPMN 2.0 diagrams, UML diagrams, P&ID diagrams, circuit diagrams, and other technical diagrams.

A central feature is the way it handles quantities in Sankey diagrams: they can be represented by the widths of connection lines or arrows. For classic flow diagrams, a single slider can be used to set line strength. The page also mentions a separate data layer for energy flow, mass flow, and other streaming quantities, and says that once a diagram is drawn, values can be changed in that data layer without manual graphical adjustments. Other listed features include magnetic snapping, assisting lines, angle indicators, a shapes and icons library, color palettes, user settings, and wizards.

Sankey Flow Show runs entirely in the browser and does not require installation. It offers sign-up for free, with an account needed to start the web app. The site also refers to a pricing section with license comparison and an account upgrade path. Sharing and collaboration functions are listed as well: users can share their work, collaborate live, view or restore previous revisions, and export diagrams to SVG, JPG, PNG, and PDF. The product is developed by THORTEC Software GmbH.
