Sankey charts are an effective way to visualize complex data relationships. Created by Charles Sankey in the late 19th century, these charts are named after their creator and are particularly useful for showing the flow or transfer of items between two or more categories.
Sankey charts use directed arrows and nodes to represent the flow of items between categories. Each arrow is pointing from the source category to the destination category, and the length of the arrow represents the volume or value of the items being transferred. The nodes represent the categories themselves, and can be customized to show additional information.
Here are some ways that Sankey charts can be used to visualize complex data relationships:
- Process Flow: Sankey charts are often used to visualize the flow of items or information through a process or system. For example, a Sankey chart of a supply chain could show the flow of goods from the supplier to the customer, highlighting any bottlenecks or areas where inventory is held.
- Inventory Management: Sankey charts can be used to visualize the movement of inventory between different locations or storage tanks. This can help identify areas of high usage or low turnover, and can inform decisions about reordering or optimizing inventory management.
- Resource Allocation: Sankey charts can be used to show how resources are allocated between different projects or departments. This can help identify areas of over- or under-allocation, and can inform decisions about resource reallocation.
- Social Network Analysis: Sankey charts can be used to visualize the flow of connections or relationships between people in a social network. This can help identify key nodes or influencers in the network, and can inform decisions about targeting marketing or building relationships.
To create a Sankey chart, you can use a variety of software tools such as Microsoft Excel, Visio, Google Sheets, or specialized Sankey charting software. These tools provide a range of customization options, including the ability to add nodes, links, and formatting to further enhance the chart’s clarity and impact.
In summary, Sankey charts are a powerful visualization tool that can help make complex data relationships easier to understand and analyze. By using directed arrows and nodes to show the flow of items or information between categories, Sankey charts can provide valuable insights into supply chains, inventory management, resource allocation, and social networks, among other areas. With the right software tools and customization options, Sankey charts offer a flexible and adaptable way to visually represent and communicate complex data.
