In the world of data visualization, Sankey charts remain a powerful and effective tool for presenting complex and detailed information. Sankey charts are used in a variety of industries, from engineering and environmental science to social sciences and economics. They are particularly useful for highlighting the flow of information or energy between different sources and destinations.
In this article, we will explore the concept of Sankey charts, how they work, and the applications of this visualization method in different industries. We will also highlight some of the key features and benefits of using Sankey charts in visualizing complex data.
What is a Sankey Chart?
A Sankey chart is a form of networked flow diagram that is used to visualize the flow or circulation of a specified amount of something from source to destination. Each point on the diagram represents a source or a destination, and the thickness of the lines connecting them indicates the amount of flow between them. A Sankey chart is different from other network diagrams in that it uses circular flow diagrams and different colors to indicate flows.
How are Sankey Charts Created?
Creating a Sankey chart requires a few steps. First, identify the information that needs to be visualized, such as the different sources, destinations, and the amount of flow between them. Next, collect the data and collect information from each source and destination to determine the flow. After collecting all the data, use a software tool, such as Microsoft Excel or Tableau, to create the Sankey chart.
Sankey Charts in Different Industries
Sankey charts are widely used in industries such as business, environmental science, social sciences, and economics. In business, for example, they are used to visualize the supply chain and visualize the flow of information between different departments. In environmental science, they are used to visualize the different water sources and their flow throughout a drainage system. In social sciences, they are used to visualize the flow of opinion or ideas, and in economics, they are used to visualize the different flows between production and demand.
What are the Key Features and Benefits of Sankey Charts?
Sankey charts offer several key features and benefits. Aesthetic: Sankey charts are aesthetically pleasing and easy to read. They can be created using various software tools and can be customized to reflect the data. Interactive: Sankey charts can be made interactive, allowing users to zoom in on specific details or to explore the data using various filters or manipulations.
