Streamlining Stories: The Chic Geometry of Sankey Diagrams

In the world of data visualization, there’s often a quest for methods to represent dynamic systems in an intuitive and engaging manner. One such method that has gained popularity for its unique ability to depict the flow of energy, materials, or money is the Sankey diagram. This distinctive visual tool, with its streamlining style and chic geometry, helps in decoding the complex and revealing the often subtle aspects of large flows within a system.

What is a Sankey Diagram?

Conceived by Irish engineer Matthew sanit in the late 19th century, Sankey diagrams are a type of flow diagram, first widely used to depict the energy flow within different systems. They feature arrows that show the direction and magnitude of the flow of a quantity through a process system, typically in units of energy or cost. They were so named after their inventor, and their distinct “streamlining” design has since been adapted to various fields for tracking a wide range of flows.

How Does a Sankey Diagram Work?

Sankey diagrams consist of a frame or several frames divided by horizontal or diagonal lines, with arrows drawn across the rectangles to show the quantity of material, energy or cost being transferred from one element to another. The thickness of these arrows represents the amount of material, energy, and money being transferred. Here are some key elements of Sankey diagrams:

Arrows: Represent the direction and magnitude of flow, with thickness proportional to the flow’s strength.
Frames: Divide the diagram, typically corresponding to different elements or steps within the system.
Connection Lines: Connect the arrows to flowing elements, showing where the material, energy or cost moves on.
Blank Space: The spaces around the connection lines are meant to represent the non-flowing components of the system.

Creating a Sankey Diagram

Creating a Sankey diagram generally involves three steps:

Define the system and select the specific flows you wish to depict. This involves understanding the quantity and direction of the flows.
Decompose your framework by identifying the different components or processes within your system you wish to track.
Design the chart by drawing lines to represent the flow of your chosen quantities, making sure the thickness of the arrows corresponds correctly to the magnitude of the flow.

Utilizing software tools like Microsoft Excel, professional diagramming software, or dedicated Sankey diagram software like SankeyMatic can streamline this process, allowing for efficient creation and customization.

Applications of Sankey Diagrams

Sankey diagrams are multifaceted tools and have found applications in a wide array of fields:

Energy Systems: Showing the efficiency and losses in the conversion and transmission of energy.
Economic Studies: Depicting the flow of money and funds within a business or economy.
Environmental Studies: Illustrating the flow of carbon and waste streams.
Environmental Accounting: Identifying sources of greenhouse gases and emissions.
Manufacturing Processes: Unraveling the flow of materials and energy through a production line.
Energy Consumption: Tracking patterns of energy use and efficiency improvements in buildings or cities.

The beauty of Sankey diagrams lies in their ability to highlight inefficiencies and opportunities for improvement at a glance. For instance, in the case of energy systems, a Sankey diagram might reveal where the greatest losses occur, prompting engineers or policymakers to focus on those areas for better efficiency.

Conclusion

The Chic Geometry of Sankey diagrams brings a unique aesthetic to the field of data visualization. By effectively streamlining complex systems, these diagrams provide invaluable insights for a broad array of applications across many industries. Their combination of simplicity and richness in information representation continues to make Sankey diagrams a tool of choice for professionals seeking to understand and improve the flow of materials, energy, or information within their systems. With advancements in technology, one can expect even more innovative applications of this timeless visual language in future endeavors.
