Sankey charts have been used for over a century to represent data and information. They have evolved from simple flowcharts to more complex visual representations of data flow. Today, they are widely used in fields such as engineering, economics, and social sciences to represent complex data flow graphs.

A Sankey chart is a type of diagram that uses overlapping rectangular blocks to represent the flow of data or information through a system. The diagram can be used to visualize the changes in variables over time or to demonstrate the flow of resources through a process.

To create a Sankey chart, the first step is to gather data in a format that can be represented in the chart. This data should be organized by source and destination, and any relevant information about the flow rate, amount, or frequency should be included.

Once the data is in the right format, the next step is to create the chart itself. This is usually done using software that supports vector graphics, such as Adobe Illustrator or Inkscape. In these programs, the data is imported, and the blocks are drawn using a specific design pattern that defines the flow of information and resources through the system.

One of the key features of a Sankey chart is that it allows for the representation of flow rates at different levels, such as minutes or hours. This can be especially useful for understanding how resources are used over time or for comparing different levels of use.

Another important feature of a Sankey chart is that it can be used to show the direction of the flow. This can be useful for understanding the flow of resources in a flowchart or for demonstrating the flow of information in a network.

In addition to flow data, Sankey charts can also be used to visualize the distribution of resources or the flow of information through a system. This can be especially useful for understanding how a system is operating or for demonstrating the efficiency of a process.

Overall, Sankey charts are a useful tool for representing complex data flow graphs. Although they may require some initial investment in design and programming, the results can provide valuable insights into how systems work and how resources are used.
