Imagine a map where nodes represent different points on a graph, and edges represent the relationships or connections between them. This kind of map is called a Sankey chart, and it’s a powerful tool for visualizing networks of data. In this article, we’ll explore the basics of creating and understanding Sankey charts and how they can be used to unlock the power of network data.
What is a Sankey Chart?
A Sankey chart is a type of network diagram that uses arrows and a series of pipes to represent the flow of data or information through different networks. The arrows represent the paths or flows, and the pipes represent the nodes or points that are connected to the flow.
There are three main types of Sankey charts used in network analysis:
- Flow maps: These charts show the flow of data or information through a single network or system.
- Network maps: These charts show the flow of data or information through multiple networks or systems at the same time.
- Activity maps: These charts show the flow of data or information among different types of activities or processes.
How to Create a Sankey Chart
To create a Sankey chart, you’ll typically start by identifying the nodes (data points) and the flows (paths or relationships). You can then choose the direction of the arrows and the type of pipes (nodes) to represent the data or information. Finally, you’ll draw the arrows and pipes on the chart to show the flow and connections between the nodes.
Once you’ve created a Sankey chart, you can use it to identify patterns or relationships within the network of data. For example, you can see if the flow of data or information in a network follows a certain pattern, such as a loop or a cycle. You can also identify if there are any sources or sinks of data or information in the network.
How to Use Sankey Charts in Real-World Applications
Sankey charts can be used in various real-world applications to visualize network data. For example, in healthcare, you can use Sankey charts to visualize the flow of patients between hospitals, doctors, and clinics. In transportation, you can use Sankey charts to visualize the flow of goods or people between different ports, airports, and cities. In education, you can use Sankey charts to visualize the flow of students between different schools, universities, and classrooms.
In conclusion, Sankey charts are a powerful tool for visualizing networks of data and unlocking the power of network analysis. By identifying patterns and relationships within the network, you can identify opportunities for improvement or innovation and create more effective and efficient organizational structures. So next time you’re working with network data, take the time to create a Sankey chart and harness the power of network analysis.
