Streamlining energy flows is a critical aspect of any organization looking to reduce waste and improve efficiency. One effective tool for visualizing energy flows is the Sankey chart, which provides a clear and concise representation of the various energy inputs, outputs, and intermediates within a system. In this article, we’ll explore how to create stunning Sankey charts using Microsoft Visio, as well as some key applications of this powerful visualization tool.

What is a Sankey Chart?

A Sankey chart, also known as a spindle chart or funnel chart, is a type of flowchart that is commonly used to represent the flow of energy, resources, or information between different parts of a system. It has a unique shape, with the inputs at the top and the outputs at the bottom, and is named after the Dutch engineer Nicolaas Sankey, who first introduced the chart in the late 19th century.

Creating Sankey Charts in Visio

Microsoft Visio is a popular charting and diagramming tool that provides a range of templates and shapes for creating Sankey charts. Here are the steps to create a basic Sankey chart in Visio:

1. Start by opening Visio and creating a new document.
2. Click on the “Insert” menu and select “Shapes.”
3. From the “Shapes” pane, search for “Sankey chart.”
4. Select the Sankey chart shape and drag it to the page.
5. Customize the chart by adding input and output shapes and connecting them with arrows.
6. You can also format the chart by adjusting colors, lines, and other visual elements.
7. Save the chart and export it in a variety of formats, including PDF, PNG, or JPEG.

Applications of Sankey Charts

Sankey charts are a powerful visualization tool that can be applied in a range of settings, from energy management to supply chain optimization. Here are some examples of how Sankey charts can be used:

1. Energy Management: Sankey charts are a useful tool for visualizing the flow of energy within a building or facility. By mapping out energy inputs (e.g., electricity, natural gas, sunlight), outputs (e.g., lighting, HVAC, appliances), and intermediates (e.g., heat, cool), it is possible to identify areas where energy is wasted or lost. This information can be used to develop strategies for energy conservation and sustainability.
2. Supply Chain Optimization: Sankey charts can also be used to visualize the flow of resources within a supply chain. By mapping out raw materials, components, and finished products, it is possible to identify bottlenecks and areas where waste or inefficiency exists. This information can be used to optimize the supply chain and improve overall efficiency and sustainability.
3. Marketing Research: Sankey charts can be used to visualize the flow of information or products through a marketing campaign. By mapping out the different channels (e.g., social media, email, print advertising), audiences (e.g., demographics, location), and outcomes (e.g., engagement, sales), it is possible to identify which channels are most effective and which audiences are most responsive. This information can be used to refine and optimize marketing strategies.

Conclusion

In conclusion, Sankey charts are a powerful visualization tool for streamlining energy flows, optimizing supply chains, and improving marketing strategies. By using Microsoft Visio to create and customize Sankey charts, it is possible to gain valuable insights into the flow of energy, resources, and information within any system. Through the use of Sankey charts, it is possible to identify areas for improvement, optimize processes, and create more sustainable and efficient systems.
