Sankey charts are a diagramming technique commonly used in data visualization to represent relationships between different categories or sources of a dataset. They are widely used in fields such as engineering, economics, and sociology to illustrate complex flows of information, resources, or energy.
The basic structure of a Sankey chart involves two main axes: one axis for the values that are flowing towards a source node, and another axis for the values that are flowing away from the source node. Typically, this is represented by the top left and bottom right portion of the chart, respectively, and the nodes representing the sources, destinations, and source-destination relationships in the dataset.
Sankey charts have a variety of applications, including:

• Project Management: Sankey charts can be used to visualize the flow of resources between different projects or tasks, helping project managers understand the dependencies and timelines involved.
• Energy Management: Sankey charts can be used to visualize the flow of energy consumption or production across different sectors or geographic areas, helping policymakers understand the impacts of energy use on the environment.
• Traffic Flow: Sankey charts can be used to visualize the flow of traffic or other moving objects across different roads or transportation networks, helping transportation managers understand the efficiency and congestion issues.

There is a wide range of tools and software available for creating Sankey charts, including spreadsheet programs like Microsoft Excel, or specialized software tools specifically designed for generating these diagrams, such as Gephi and Visualizations Project.

Sankey charts offer a powerful tool for illustrating complex relationships between different sources, destinations, and flows of information, energy, or resources. By visually representing these relationships, they facilitate the better understanding of the patterns, trends and impacts of these flows, and can help organizations and policymakers identify areas for improvement and make informed decisions.
