Sankey charts are a unique and visually stunning form of data visualization, which have gained increasing popularity in recent years. Named after Matthew Henry Phineas Riall Sankey, an engineer who developed the concept in the late 19th century, Sankey charts are a powerful tool that can help us to understand complex relationships, processes and data flows. In this article, we will explore the power of Sankey charts and how they can help us to create compelling visual journeys, and delve into the details of Sankey chart creation and applications.
Creating Sankey Charts
Creating a Sankey chart involves several key steps that require careful consideration. First, we need to identify the key data sets that we want to visualize, which could be related to energy consumption, resource allocation, or any other process or flow. Next, we need to define the nodes, which represent the entities in our data set, and the links that connect them, which represent the flows between those entities.
Once we have identified our data sets and defined our nodes and links, we can begin creating the chart. There are a number of tools and software options available for creating Sankey charts, including Microsoft Excel, Tableau, and R, among others. Each tool has its own strengths and weaknesses, so it is important to choose the one that best suits your needs.
In order to create a compelling Sankey chart, it is critical to ensure that the chart is readable and easy to understand. This means using clear and concise labels, consistent colors, and appropriate thickness for the links. Additionally, it is essential to ensure that the chart is aesthetically pleasing and visually engaging, which will help to draw attention and convey the intended message effectively.
Sankey Chart Applications
Sankey charts have a wide range of applications across a number of industries and fields, including energy and sustainability, supply chain management, finance, and more. In the energy sector, Sankey charts are commonly used to visualize the flow of electricity from power plants to consumers, highlighting the various sources of electricity and their relative contributions to the overall mix. In the field of supply chain management, Sankey charts are used to visualize the flow of products from suppliers to manufacturers to retailers, enabling organizations to identify bottlenecks and optimize their processes.
Sankey charts can also be used to visualize financial data, such as the flow of money through a company’s balance sheet, or the distribution of revenue across different product lines. By providing a clear and intuitive visual representation of complex data flows, Sankey charts can help to simplify and communicate these relationships effectively, making them an essential tool for data visualization and analysis.
Conclusion
Sankey charts are a powerful and versatile tool for data visualization, providing a visually engaging and intuitive way to explore and understand complex data flows. By carefully considering the data sets and elements that we want to visualize, as well as the tools and software options available, we can create compelling Sankey charts that effectively communicate our intended message. Whether we are visualizing energy consumption, supply chain management, or any other data set, Sankey charts offer a unique and valuable way to unlock the hidden insights and patterns within our data.
