Sankey charts are a powerful tool for visualizing relationships between different data sources, particularly when the relationships are flow-based. In this article, we’ll take a deep dive into the intricacies of how Sankey charts can be used for flow visualization, and explore some of the practical applications that can be explored with this method.
Sankey charts are a type of network diagram that allows for the visualization of flows between different elements. These elements can be anything from people, organizations, or data values to physical objects, processes, or relationships between them. The basic structure of a Sankey chart consists of two arrows coming out from each node, one for the incoming flow and one for the outgoing flow.
In the simplest forms, Sankey charts can be used to represent relationships between data sources, such as time series data, or between different organizations. To visualize the flow between these different sources or sinks, the Sankey chart can be customized with different color or font styles, and different colors can be used for different types of flows (such as incoming or outgoing, or from a source to a sink).
In addition to the basic Sankey chart, Sankey dashboards can also be used to represent flow data over time, and more complex data visualizations can be used to create a comprehensive overview of the relationships between different elements.
One of the key benefits of Sankey charts is that they allow for the visualization of complex relationships between multiple data sources or processes, without requiring an exhaustive explanation or extensive documentation. This makes Sankey charts an excellent tool for identifying patterns and trends within a large dataset, and for identifying the areas that require more detailed inspection.
One practical application of Sankey charts is for the analysis of energy consumption data or flow from water treatment plant operations. In these cases, Sankey charts can be used to visualize the flow of different materials between different points, such as the production of materials from raw materials at the material source, or the distribution of raw materials throughout a facility. This information can be used to identify opportunities for optimization, such as reducing waste or increasing efficiency.
Additionally, Sankey charts can be used in the field of computer science to visualize the flow of different data flows (such as the flow of data between different applications), or the flow of information between different data sources (such as the flow of data from sensors to remote servers). This can be used for monitoring the performance of different system components and identifying anomalies, which can be used to improve the efficiency and reliability of the system.
Another practical application of Sankey charts is in supply chain management. Sankey charts can be used to represent the flow of raw materials and finished goods between different suppliers and distributors, identifying bottlenecks and areas for improvement in the supply chain.
Sankey charts can also be used to visualize the relationship between different variables in a dataset, such as the flow of different variables into different categories, or the flow of different variables between different elements. This can be used for identification of patterns, the creation of predictive models, and for optimization of a given process.
In conclusion, Sankey charts are a powerful tool for visualization of relationships between different data sources in relation to a flow-based system. As such, they can be used for a variety of practical applications, including data analysis, supply chain management, computer science, and more. With the increasing use of data visualization in fields such as finance, healthcare, and technology, Sankey charts have become an essential tool for analyzing complex relationships between different variables.
