Sankey charts are a powerful tool for visualizing information flow between different elements. These charts are often used in fields such as economics, public health, engineering, and geography. In this article, we will explore the secrets of how to create and use Sankey charts, including some important tips and tricks for achieving clarity and effectiveness.
What Are Sankey Charts?
Sankey charts are a type of diagram that shows the relationship between different elements or elements and their flow of information or resources. They are named after Sir John Sankey, who is often credited with coining the term “social network analysis.”
One of the key features of Sankey charts is their ability to visually represent complex information flow. For example, you can use Sankey charts to illustrate a company’s supply chain, or to show how different regions in a country are interconnected in a trade network. The chart itself is a network of nodes and lines, with each node representing a different element and each line connecting the elements.
Creating a Sankey Chart
Creating a Sankey chart can be a bit challenging at first, but it’s not difficult once you get the hang of it. Here are some tips for getting started:
1. Choose Your Elements: One of the first things you need to consider is what elements you want to include in your chart. These may include individuals, organizations, physical resources like land or machines, or other non-physical resources like ideas or energy. Consider the complexity of your data and which elements you think are most relevant.
2. Choose Your Layout: Once you know which elements you want to include, you can start to think about where those elements will go on the chart. You may want to use a traditional layout, where the nodes and lines are arranged in a ring, or you may want to adopt a more dynamic layout, where the structure of the chart changes as you navigate through it.
3. Use Diagrams: Sankey charts are often created using software like Microsoft Visio or Lucidchart, but you can also use a simple drawing pad or a free online tool. To create a Sankey chart, use a tool that allows you to add nodes, lines, and labels, and customize the appearance of your chart as needed.
Using Sankey Charts
Once you have created a Sankey chart, you can use it to explore and understand complex information flow. Here are some tips for using Sankey charts:
1. Start with the Flow: One of the most important things to remember when using a Sankey chart is to start with the flow. Look for lines or nodes that show the main directions of information flow, and focus on the elements that are involved in those flows.
2. Look for Patterns: Sankey charts can show patterns in information flow that you might not have noticed. These patterns can be used to infer causal relationships or to create new insights.
3. Look for Exceptions: Sankey charts can also show exceptions in information flow, such as outliers or unexpected changes. These can be used to highlight important information that was not included in the initial data collection.
In conclusion, Sankey charts are a powerful tool for visualizing complex information flow. By understanding the key features of Sankey charts, such as their ability to represent information flow and their flexibility in layout and appearance, you can create and use these charts to understand and explore data in new and insightful ways.
