Sankey charts have been around for over two centuries and they have been used to visually represent the flow of energy, resources, and other data for as long as that. While Sankey charts may not be as common as other chart types, they hold a unique power that allows users to visualize the flow dynamics of data in a way that simple charts cannot. This power lies in their ability to show the direction and magnitude of flows between nodes, thereby helping users to understand the relationships and dependencies within the data.
Creating Sankey charts involves several steps, starting with setting up the data. The data should include information about the source, the target, and the value of the flow between them. The source and target nodes should be clearly defined, and the flows should be represented by arrows, which can be styled according to their size and color. Additionally, the chart can include labels for each node and arrow to make it easier for the user to understand the data being presented.
Once the data is set up, the next step is to decide on the layout of the chart. A Sankey chart typically has a layout that shows the flow in a top-down perspective, with the source nodes at the top and the target nodes at the bottom. However, the chart can also be designed to show the flow in a side-to-side perspective, depending on the type of data being presented.
Sankey charts can be used in various fields, and there are many applications for them. One common use of Sankey charts is in energy modeling. By representing the flow of energy between different sources, such as coal, oil, and renewables, Sankey charts can help users understand the energy mix of a country or region. Another application is in supply chain management, where the flow of goods and materials can be visualized to help identify inefficiencies in the system.
Another popular application of Sankey charts is in data science, particularly in the field of network analysis. By representing the flow of information or data between different nodes in a network, Sankey charts can help users understand the relationships and dependencies within the network. Furthermore, Sankey charts can also be used in the field of epidemiology to show the flow of disease transmission between different populations.
One important aspect of creating a Sankey chart is the selection of tools for creating the chart. While Sankey chart creation can be done manually using graphical editors, most people prefer using specialized software or online tools. Some popular tools for creating Sankey charts include Microsoft Power BI, Tableau, and Sankey.io. These tools offer a wide range of features and customization options, making it easy for users to create professional and customized Sankey charts.
Sankey charts are a powerful tool for visualizing flow dynamics that can help users understand and analyze complex data in a clear and concise way. While they may not be as common as other chart types, their unique ability to represent the direction and magnitude of flows makes them increasingly popular in various fields such as energy modeling, supply chain management, data science, and epidemiology. By using specialized software or online tools, users can create customized Sankey charts that provide valuable insights into their data.
