Sankey charts have become increasingly popular in the world of network analysis and visualization, and for good reason. These charts are visually stunning and can provide a wealth of valuable insights into complex network structures. In this article, we will take a closer look at how to create a Sankey chart and some of the applications it can be used for.
What Are Sankey Charts?
A Sankey chart is a type of diagram that uses a combination of lines and bars to illustrate the flow of resources or information between different elements. The chart is typically represented as a diagram with a main trunk line, which represents the main flow of information or resources, surrounded by smaller lines that branch out to indicate the flow of resources between different elements. Sankey charts are often used to visualize the structure and flow of a network or information system.
Using Sankey Charts
There are a variety of software and tools available for creating Sankey charts, including Microsoft Excel and Canva. These tools allow you to easily create a Sankey chart using existing data or by inputting your own data.
To create a Sankey chart, you will first need to define your network or data structure. This can be done by entering the data into a spreadsheet or database, or by importing data from a document or spreadsheet.
Once you have defined your network or data structure, you will need to select the main trunk line for your chart. This is the line that represents the flow of information or resources. The other branches in the Sankey chart will represent the different elements or components of the network.
As you select each branch, it will be represented by a line and a corresponding bar, which may be a shape, line or combination of both. The shape of the bar will also indicate the type of flow or resource being represented on that branch.
Overall, creating a Sankey chart is a relatively simple process, and once you have the basics down, you can use it to visualize and explore complex network structures.
Applications of Sankey Charts
Sankey charts have a wide range of applications in different areas, including network analysis, supply chain management, and data visualization. For example, Sankey charts can be used to visualize the flow of resources between different elements in a supply chain, or to visualize the flow of information between different parts of a company or organization.
Sankey charts can also be used to explore complex data structures, such as the relationships between different elements in a network or data set. These charts can provide a visual representation of the relationships between different elements in a network, which can then be used to explore and analyze the data.
In summary, Sankey charts are a powerful tool for exploring and visualizing complex networks and data structures. By selecting the main trunk line and customizing the other branches of the chart, you can create a Sankey chart that is tailored to your specific needs and can provide valuable insights into your data or network. With the availability of a wide range of software and tools for creating Sankey charts, anyone can use this powerful visualization tool to explore and understand their data or network.
