Sankey charts are a type of data visualization tool that is useful for understanding complex network data. These charts are particularly effective at displaying information about relationships between different entities or events in a network. In this article, we will explore the power of Sankey charts and provide an in-depth look at how to create and use them effectively.
First, let’s define what a Sankey chart is. A Sankey chart is a visual representation of a network, where the flow of data along the edges of the chart can be easily tracked. The main elements of a Sankey chart include:

1. Source nodes: These are the entities or events being measured in the network.

2. Target nodes: These are the entities or events that receive data from sources.

3. Edges: These represent flows or flows between sources and targets.

4. Fill color: This determines which source node receives more data than other nodes.

5. Gradient colors: This allows you to compare different sources.

6. Labels: These are used to label each node and edge with information about its value or flow.

Now that we have defined what a Sankey chart is, let’s explore how they can be used to understand complex network data.
Sankey charts can be used to visualize relationships between different entities in a network, such as customers, suppliers, or employees in an organization. For example, you could use this type of chart to show how supply chains work between different companies or how customer preferences change over time.
Another common application for Sankey charts involves understanding environmental impacts caused by industrial activity. A company might want to track emissions from factories so they can see where their biggest contributors are and identify areas for improvement.
To create a Sankey chart using Microsoft Excel:
1. Open Microsoft Excel and make sure you have your input table with columns labeled properly (nodes on left side, edges on right).
2. Select one node from one column (e.g., “Customer”) that represents one entity (a source) that is being measured
3-4) Drag it over all corresponding columns until it reaches target nodes (each “Customer” should connect directly back to itself)
5-6) Fill each edge with values representing flows
7-8) Use gradient colors for visual comparison purposes
9-10) Label each node and edge accurately with corresponding text
