Sankey charts, also known as directed acyclic networks or DANN, are a type of visualization tool used to visually represent data flow in complex systems. These charts are created by dividing the system into multiple “nodes” or “components” and connecting those nodes with a series of “pipes” or arrows that represent the flow.
Sankey charts have become increasingly popular in many fields, including business analytics, engineering, economics, and social sciences, as they provide a clear and concise way to represent and analyze complex data flow. In this article, we’ll take a step-by-step look at how to create and use Sankey charts to visualize complex data flow.
Step 1: Identify the Data to Be Represented
Before creating any visualization, the first step is to identify the data that you want to represent. In the case of Sankey charts, this data typically consists of the flow of resources, goods, or information between nodes.
Step 2: Assign a Label to Each Node
Once the data has been identified, the next step is to assign a label to each node in the system. These labels should be descriptive and provide information about the node, such as the type of resource, the origin, or the destination.
Step 3: Create the Nodes
Next, create the nodes and pipes for the system. The nodes represent the different systems or components that the data flow is represented on and the pipes represent the flow of data between those nodes.
Step 4: Connect the Nodes with Pips
Using the information about the flow of resources or data, connect the nodes with arrows to represent the flow. The length of the arrow should correspond to the flow rate or volume of the data.
Step 5: Add Labels to the Arrows
Lastly, add labels to the arrows indicating the direction and volume of the flow. The length of the arrow should correspond to the flow rate or volume of the data, and the direction of the arrow should indicate the flow from one node to another.
Step 6: Color-Coding and Annotations
Additionally, color-coding and annotations can be added to highlight certain aspects of the data flow. For example, the flow rate can be represented by color-coding or annotations highlighting specific values.
Step 7: Customize for Customization
Finally, the visualization can be customized to fit the specific needs of the application. This could include adding specific annotations or color-coding based on the analysis or context of the data.
Using Sankey charts to visualize complex data flow is a powerful tool that can help you gain a better understanding of the movement and direction of resources in a system. Additionally, it can be customized to fit the specific needs of the analysis and help you see the big picture of how different parts of a system are interconnected. Whether you’re working with business data, engineering diagrams, or social data, Sankey charts can provide a clear and concise representation of complex data flow, making it easier to analyze and interpret.
