Flowmapping Fundamentals: Unveiling the Visual Elegance of Sankey Symphony

In an era where data visualization helps make sense of complex systems, the Sankey chart emerges as a shining example of how visual elegance can illuminate intricate details. This guide delves into the fundamentals of flowmapping, the art of creating Sankey diagrams, and their broad applications across various sectors.

What is a Sankey Chart?

A Sankey chart is a type of flow diagram that diagrams the transfer of energy or material through a system. Flow maps can visualize the magnitude of inputs and outputs among different components of a system, making the energy or material flow rates understandable at a glance.

The hallmark of a Sankey chart is its distinctive “streamlines” — arrows that branch to wider and narrower sections, indicating the relative flow of material or energy. The widths of these streams represent the quantity of material or energy transferred, with wider sections implying a higher flow rate.

The Fundamentals of Creating Sankey Diagrams

Creating a Sankey chart involves several fundamental steps:

Define Your Data Flow: Begin by defining the system you wish to visualize. Outline the inputs and outputs, and how information or energy moves from one state to another.
Map Components: Identify the different components within your system and their roles. Use unique shapes and labels to represent these components visually.
Construct the Streamlines: Arrange streamlines to show the direction and magnitude of flow between components. The width of the streams must accurately represent the relative flow rate.
Link Components: Connect the components with streamlines and indicate the flow direction. If the flows are variable, use different colors or patterns to encode the variability information.
Adjust for Balance: Ensure that the system’s inputs and outputs balance — that is, all inputs should cumulatively equal the sum of all outputs, within an acceptable margin of error.
Add Context: Provide legend, scale, and any other annotations to convey additional information that might be useful to readers.
Review and Iterate: Once your Sankey chart is created, review it to make sure it represents the system accurately and that it is easy to understand.

Applications of Sankey Diagrams

Sankey charts, with their ability to convey quantitative information in a visual format, are applied across a wide range of fields:

Energy Systems: Illustrate the efficiency of power plants, the energy conversion in various processes, and the flow of energy through appliances or buildings.
Economic Analysis: Visualize the flow of money, resources, or environmental impacts within economies, industries, or supply chains.
Environmental Impact: Show the flow of water, air pollution, or other environmental resources and their cumulative effects.
Data Flow in Software Development: Map the paths data takes through a program, helping developers identify inefficiencies or understand system performance.
Biomedical Systems: Demonstrate the flow and distribution of fluid, cells, or other elements in living organisms.
