About Sankey Diagram
Professional drawing tool to create Sankey Diagrams. These diagrams show flows, where the width is proportional to the rate of flow. The diagrams can be created interactively, adding flow sources and sinks, moving nodes and flows around, editing colors, and more. The diagrams can be exported as a .PDF or .PNG, shared by email, messaging, and saved to the Camera Roll. A .SNK file version of your diagram can be shared by email with other Sankey Diagram app users, who will be able to load and edit the diagram. You can also create a diagram by importing a .CSV file from an email attachment or iCloud. The diagram is automatically created from the data in the spreadsheet. Edit diagrams on any of your devices using iCloud.
