Sankey charts are an intuitive and powerful way to visualize data flows and the relationships between different entities. In this article, we’ll explore the power of Sankey charts and provide you with the necessary knowledge to create and interpret them effectively.
Overview of Sankey Charts
A Sankey chart is a type of diagram that displays the flow of data or information from one entity or source to another. It’s often used to visualize the movement of resources, people, products, or other data items from one location to another. This type of chart uses flow lines and labels to show the direction and magnitude of the flow.
Benefits of Sankey Charts
Sankey charts offer several benefits when it comes to data visualization, including:
– They are easy to understand and interpret
– They provide a visual representation of data flow, making it easier to see which entities or sources are driving the data flow
– They make it easy to compare and contrast different data flows
– They can be adapted to display different types of data, such as financial flows, natural resource flows, or social flows.
Types of Sankey Charts
There are two main types of Sankey charts: directed and undirected. The directed type displays the flow of directed data, such as resources, people, or products flowing from one entity to another, whereas the undirected type displays the flow of undirected data, such as financial flows or market flows, without specifying its direction.
In addition to these main types, Sankey charts can be modified and customized to display additional information, such as the magnitude of the data flow, the flow direction, and the duration of the data flow.
Creating Sankey Charts
Creating a Sankey chart involves several steps, including:
1. Determine the data to be visualized
2. Identify the sources and destinations for the data flow
3. Identify the flow lines based on the data flow direction
4. Draw the flow lines on the chart
5. Label the flow lines with the flow magnitude and direction
6. Customize the chart as desired
Examples of Sankey Charts
Here are some examples of Sankey charts that use different data flows and data flows directions:
1. Financial Flow: This Sankey chart depicts the flow of money from one financial entity to another, such as a company’s bank account to another company’s bank account, or a customer’s credit card to another customer’s bank account.
2. Product Flow: This Sankey chart visualizes the flow of products from one factory to another, or the flow of a product from one warehouse to another.
3. Social Flow: This Sankey chart visualizes the flow of social interactions, such as the flow of messages between users on a social media platform, or the flow of interactions between different communities.
Conclusion
Sankey charts are a powerful tool for visualizing data flows and relationships between different entities. They offer clear and intuitive information, making it easy to understand and compare different data flows. By understanding the benefits of Sankey charts and following the steps involved in creating them, you can effectively visualize different data flows and relationships in your data.
