Sankey diagrams are a unique tool for visualizing complex data relationships. With their simple, elegant design and ability to convey intricate network structures, Sankey diagrams are widely used in scientific discovery, social science analysis, and data visualization. To unlock the secrets of Sankey diagrams and use them effectively, understanding their principles, elements, and application are crucial. In this article, we will explore the fundamental concepts and applications of Sankey charts, providing you a thorough understanding that will empower you to create beautiful and effective Sankey diagrams.
What is a Sankey diagram?
A Sankey diagram, or flow diagram, is a type of diagram that shows how different elements in a system move or flow between each other. It uses a network of bars or boxes, often referred to as nodes, to represent the source, destination, and flow direction of each element. The bars are typically connected to each other by lines or arrows representing the flow direction.
Basic structure of a Sankey chart consists of three main sections:
1. Source/destination node: It is the starting or ending point of the flow. It is characterized by a label, usually a symbol (e.g., circle, square) and color.
2. Flow Direction bars: This section represents how the elements flow between the source and destination nodes. The bars can be of any shape and size, and their direction represents the flow direction.
3. Connectivity between nodes: Sometimes, a third section (or “network”) might be added to represent the flow of elements between nodes.
How to Create a Sankey Chart
To create a Sankey chart, you will need to:
1. Collect the data: To create a Sankey diagram, you need to have a dataset or a network of elements that you want to represent. The data should include the source and destination nodes, as well as the flow direction.
2. Choose the layout: Sankey charts are commonly drawn using a network layout. The most common layout is the stack layout, which allows the bars to stack and line up with each other to create a neat visual arrangement.
3. Organize the data: Once you have the data and the layout, organize the data in the bars as follows:
– Source node: top section of the diagram
– Destination node: bottom section of the diagram
– Flow direction: down the central part of the diagram
4. Draw the bars: Start by drawing the bars with correct layout, size, and shape, aligning them with the nodes
5. Fill in the bars: Fill in the bars as they represent the direction and flow of elements. This can be done by using a filling technique to indicate the direction or by coloring the bars to differentiate between different elements.
6. Connect the bars: To link the nodes, use lines or arrows to represent the flow direction. The arrows can be made visible or hidden by formatting the bars.
Elements and Applications
In scientific exploration and scientific discovery, Sankey diagrams are useful for representing the flow of information or data between different elements. They are also often used in social science analysis to represent the relationships between different groups or individuals. Sankey diagrams are also commonly used in data visualization, where they help to simplify complex data representations.
Data Visualization: A tool for improving communication and efficiency
Data visualization is an essential aspect of today’s data-driven world. Sankey diagrams have been used in many industries such as healthcare, government, finance, and many others. They help in presenting complex networks of data in a simple and intuitive way that can be easily understood by many people. Sankey diagrams are particularly useful for complex network analysis, trend-line forecasting, and data visualization for dashboards.
For businesses, they provide a visual representation of how the data is flowing in and out. Sankey diagrams help in enhancing the understanding of complex data by making it easier to see the flow of data from source to destination. They can also be used for tracking the cost and resource allocation for a project, which can be beneficial for project management.
Application in educational settings
For students, Sankey diagrams can help them understand concepts more effectively. The layout and dimensions can be adjusted to match the learning style of each child. This can make them more interactive and engaging for students, leading to better understanding of complex networks and systems.
Applications in the Engineering and Chemical Industry
Sankey diagrams are also of high importance in the engineering and chemical industry. These diagrams can help in visualizing the chemical reactions in different stages. They can help engineers identify possible bottlenecks in the process and predict the future behavior of the system.
Conclusion
Sankey diagrams are an excellent tool for visualizing complex data relationships. By understanding their principles and applications, you can use them to create beautiful and effective diagrams that simplify complex systems. Whether you are a scientist, a student, or an engineer, Sankey diagrams can help you understand your networks more clearly, provide a way to identify potential bottlenecks or issues, and more.
