Title: Unraveling Information Flow: A Comprehensive Guide to Sankey Charts

Sankey charts are a type of diagram that represents the flow of information or data. They are commonly used in fields such as business analysis, communications, and research to display relationships and dependencies between the elements involved in an analysis. If you’re new to constructing and analyzing Sankey charts, this article will guide you through the basics and explain their applications.

Definition of Sankey Chart

Sankey charts consist of interconnected circles to represent the relationships between nodes (sources and sinks) and the flow of information between them. The circles are arranged in a sequence that reflects the direction of the flow, and their size represents the intensity of the flow. The circles are colored to denote the source or sink, and their position indicates the direction of flow.

Types of Sankey Diagrams

There are two main types of Sankey charts: simple and detailed. Simple sankey charts focus on outlining the flow of information between two elements, whereas detailed sankey charts show multiple flows in a single diagram.

Here’s how to create simple sankey charts:

Step 1: Define the Nodes and Directions

Start by listing all the nodes in your analysis. Each node can represent an individual, organization, or event. The direction of flow should be specified for each node, typically reflecting the origin or destination.

Step 2: Draw the Circles

Use circles to represent each node. Make sure that the circles are large enough to represent the entire value of the flow associated with that node. You can color circles based on which way the flow is going.

Step 3: Draw the Lines

Draw lines between the circles to represent the flow of information between the nodes. Use arrows on the lines to denote the direction of the flow. The thickness of the lines will reflect the strength of the flow.

Step 4: Add Labels and Symbols

Label each circle to clarify its meaning and add symbols to represent the origin or destination of the flow. This will make it easier to interpret the diagram.

To create detailed sankey charts:

Step 5: Add More Nodes

As your analysis grows, you’ll need to add more nodes to represent the relationships between the main nodes. You can use any number of nodes as long as they reflect the real-world structure of your analysis.

Step 6: Add More Flows

To create detailed sankey charts, you’ll need to create more flows for the main nodes. These flows can represent multiple elements, events, or sources.

Step 7: Add More Circles and Lines

With more nodes, you’ll need to draw more circles and lines to represent the relationships between the nodes. This will create a more complex diagram that reflects the depth of the analysis.

Applications of Sankey Charts

Sankey charts have numerous applications in various fields, including:

1. Business Analysis: Sankey charts can help businesses analyze the supply chain, production flows, and customer relationships. They can show relationships between suppliers, partners, and customers to identify bottlenecks and improve efficiency.

2. Communications: Sankey charts can help organizations analyze their communication networks and identify information superfluity. By identifying sources and sinks, communication planners can optimize the flow of information to increase efficiency and reduce costs.

3. Research: Sankey charts can be used to examine social and economic networks in research projects. By analyzing the flow of ideas, events, and relationships, researchers can identify the strengths and weaknesses of existing networks and develop new insights.

Conclusion

Sankey charts are an effective tool for explaining complex information flows in a simple and informative way. By following the steps outlined in this article, you can create diagrams that represent information flow, communicate valuable insights, and help organizations make data-driven decisions. With practice, you’ll soon be creating diagrams that convey meaningful and effective information.
