Sankey diagrams are a type of flowchart that utilize different types of segments or nodes to represent different types of data. They are used to show relationships and interdependencies between different elements and can be used for a wide variety of purposes such as product flow, energy flow, human resource movement, or chemical flow. In this article, we will explore the power of Sankey diagrams and how they can be used to unlock insights from complex and intricate data.

Definition and Overview
A Sankey diagram uses multiple overlapping rectangles or segments to represent different types of data. Each segment represents a different type of data, with the thickness of the bars indicating the frequency of the data. The overall flow of the diagram represents a connection between different elements. Sankey diagrams are also known as flow charts, flow graphs, or sector diagrams.

Applications of Sankey Charts
Sankey diagrams have many applications in various industries such as manufacturing, finance, oil and gas, transportation, and energy. They are used to visualize flow, movement, and data from various sources, which makes it easy to understand relationships and patterns. Some of the common applications are:

• Flow analysis to identify key areas that need improvement in a company
• Product flow analysis to identify bottlenecks and improve efficiency
• Human resource flow analysis to identify areas of bottlenecks and optimize workloads
• Chemical flow analysis to identify areas of inefficiency in the production process

Creating a Sankey Diagram
Creating a Sankey diagram involves selecting shapes for each segment and connecting each segment to a different element or data source. The shapes used for the segments can be different, but they should be recognizable and represent the data flow. Once shapes are selected, the connecting lines should be drawn in a consistent direction. The thickness of bars should not be too thick or too thin, as this can affect the overall readability and meaning of the chart.

Interpreting a Sankey Diagram
An important part of using a Sankey diagram is understanding the data flow and the relationships between different elements. The overall flow of the diagram should be clear and intuitive, with different colors used to indicate different sources and destinations. The thickness of the bars can be used to indicate the frequency of data. Also, the shape and color of each segment can be used to highlight specific areas or data flow.

Limitations
While Sankey diagrams are a powerful tool for understanding flow patterns and relationships, they have some limitations. For instance, they may not be the best tool for visualizing highly correlated data. The diagram may not adequately represent the data as it is. This is because Sankey diagrams focus on the direction of the flow and not on the shape and quality of the segments. Additionally, it may take a bit more time to create and interpret a Sankey diagram than other visualization methods.

Conclusion
In conclusion, Sankey charts offer a unique and versatile way of visualizing data. They can be used to unlock insights from complex and intricate data, making it easy to understand relationships and patterns. While they have some limitations, they are still a valuable tool for understanding flow and relationships. Incorporating Sankey charts into workflows can help companies optimize their processes, improve efficiency, and drive business growth.
