Sankey chart is a type of network diagram that is used to represent complex relationships between factors. It is a powerful tool for visualizing data and displaying relationships between different variables. This article will explore the power of Sankey charts and how they can be used to create a visual journey through data visualization.
The Basics of a Sankey Chart
A Sankey chart is a network diagram that is used to represent the flow of information or resources from one source to another. It is a type of flow diagram that is similar to a network diagram, but it uses a different symbol to represent the flow of information or resources from one source to another. The most common symbol used in a Sankey chart is a pipe, which is a funnel-shaped channel that represents the flow of information or resources from one source to another.
Sankey charts are created using a series of elements that represent the different factors or variables involved in the flow of information or resources. The size and position of each element in the chart represent the amount of information or resources that flow through the relationship between the factors. This allows the viewer to easily identify the flow of information or resources from one source to another and see where the flow breaks down.
Sankey Charts in Practice
Sankey charts can be used in many different fields, from science and engineering to business and finance. However, it is most commonly used in the fields of medicine and health care to visualize the flow of blood, nutrients, hormones and drugs through the body. It is also used in the field of computer science to visualize the flow of information through the files and databases of a computer system.
The use of Sankey charts requires a good understanding of the underlying data, as it is a tool for visualizing relationships between different factors. The user must be able to identify the key relationships between the variables and use the flow to see where the flow breaks down, and how this affects the overall result.
Creating a Sankey Chart
Creating a Sankey chart is a relatively simple process, as it is based on a few key components:
- Source / target: The source of the flow of information or resources is represented by the flow from a symbol, and the target of the flow of information or resources is represented by the flow into a symbol.
- Flow: The flow of information or resources is represented by a series of pipes.
- Size: The size of each pipe in the chart represents the amount of information or resources flowing through the relationship.
- Color: The color of each pipe in the chart can be used to represent different factors and their importance.
Using Sankey Charts in Data Visualization
Sankey charts can be used to create a visual journey through data visualization in many different ways. For example, in the field of finance, a Sankey chart can be used to visualize the flow of money between different sources and targets. In the field of research, it can be used to visualize the flow of information between different subjects and topics.
Sankey charts can also be used in the field of economics to visualize the flow of money and resources between different factors, such as wages, prices, and taxation.
In conclusion, Sankey charts are a powerful tool for visualizing data and displaying relationships between different variables. They can be used to create a visual journey through data visualization, allowing users to easily identify and understand the flow of information and resources from one source to another. Whether used in the field of finance, medicine, computer science, or any other field, a good understanding of the data is essential to effectively create a Sankey chart.
