Flowy Insights: The Sankey Chart Sensation Unplugged

In this digital age, data visualization plays a crucial role in making complex information more accessible and understandable. Among the wide array of tools and charts available, the Sankey diagram stands out as an information viz powerhouse, offering a visually intuitive way to depict the flow of materials, energy, costs, and other quantitative data. “Flowy Insights: The Sankey Chart Sensation Unplugged” delves into the intricacies of Sankey chart creation, their applications, and why they have become an indispensable resource in the data visualization arsenal.

Understanding Sankey Diagrams

Sankey charts are named after English engineer, William John Macquorn Rankine, who proposed the concept while discussing the losses in the steam engines of his time. They are flow-oriented diagrams that use directed arrows to depict the flow and direction of materials, fluids, or energy through a process or system.

The Sankey diagram is designed with the following features:

Flow Representation: The width of the arrow indicates the magnitude of the flow at any point along the path. The wider the arrow, the greater the flow.
Integration: The flow of energy is integrated into an overall network and is shown as a stream connecting different components or processes.
Efficiency Indicators: By comparing the widths of input and output arrows, one can quickly gauge the efficiency of a system or process.
Energy Flow: Sankey charts primarily focus on displaying energy flows, but they are adaptable and can represent other types of data streams.

Creating a Sankey Chart

Creating a Sankey chart is a multi-step process that requires careful planning and accurate measurement:

Data Collection: Gather your numeric data for the processes, systems, or entities you wish to visualize. Always ensure the data is accurate and up-to-date to avoid misinterpretations.
Flow Determination: Establish the starting and ending points of the flows, where they merge, and any branches they take during the journey.
Efficiency Assessment: If relevant, measure the efficiency of the flow, which will influence the width of the Sankey arrows as some arrows should be thin (representing small energy loss) while others should be very broad (representing large inputs).
Chart Design: Choose the right software to create the chart or use tools that specifically support Sankey diagram generation. Programs like Microsoft Excel, Google Sheets, and specialized software such as Sankey Diagrams or ExcelSankey are all viable options.
Customization: Customize the diagram by adjusting the thickness of the arrows to represent the magnitude of the flow, adding labels, and choosing color schemes to enhance readability and clarity.

Applications of Sankey Charts

Sankey diagrams have a broad spectrum of applications across various disciplines, including:

Energy Management: Tracking energy flows in power generation, heating, ventilation, and air conditioning (HVAC) systems.
Finance: Visualizing the flow of money within an organization or tracking the sources and destinations of funds.
Environmental Science: Tracking the flow of waste materials, or illustrating the movement of species within ecosystems.
Supply Chain: Demonstrating how materials move through the supply chain or illustrate the journey of a product in the manufacturing process.
Economic Modelling: Modeling financial investments and illustrating capital flows and their effects.

The Impact of Sankey Charts

Sankey charts are not only powerful tools for data visualization but also serve to enhance decision-making. By visualizing complex systems in an intuitive manner, they help stakeholders understand the big picture, identify inefficiencies, and make more informed decisions.
