Introduction

Sankey diagram is a type of visualization tool which is widely used in various fields like engineering, finance, and science. One of the key features of the Sankey chart is that it can be used to visualize the flow of information or data from one point to another. This type of visualization is particularly useful when there are dependencies between different parts of a system or when we are trying to understand the relationship between two or more variables. This article will explore the power of Sankey charts and their potential applications.
The Meaning of Sankey Chart

Sankey chart is a type of diagram used to visualize the flow of information or data in a network. It is also known as a network diagram or directed graph. Each element in the chart is represented by a node, and the edges represent the relationships between the nodes. A Sankey chart can be used to draw the flow of information or data through a system, with the elements of the network linked by directed arcs.
Sankey charts are particularly useful when we want to visualize the flow of information or data within a system. This can be useful when we want to understand the relationship between the different parts of a system, such as how data flows between different departments or departments across different levels. Sankey charts can also be used to visualize the flow of information or data in a complex network, such as a manufacturing or transportation system.
The Concept of Dependency

In a Sankey chart, the relationships between different elements are represented by arcs that are directed from the source nodes to the destination nodes. This means that the more arcs there are, the more dependent the elements are on each other. This concept of dependency is also known as a directed acyclic graph (DAG) in computer science.
The dependency between two elements is represented by the size of the arc. A larger arcs indicates a stronger dependency between the two elements. This can be useful when we want to understand the relationships between different elements in a network.
Conclusion

Sankey charts can be used to visualize the flow of information or data, which can be useful in understanding the relationship between different elements of a system. When we want to represent the flow of information or data in a network, a Sankey chart can be a powerful tool. It can also be used to represent the flow of information or data in a complex network, which can be useful when we want to visualize the relationships between different elements of a system.
