Introduction
Sankey charts are a valuable tool for visualizing the flow of information in complex systems. These charts use a series of bars to represent the quantity of resources (be it people, money, or data) moving between different entities or processes. In this article, we will take a closer look at the creation and applications of sankey charts, as well as how they can be used to transform information in organizations.
Creating a Sankey Chart
The first step in creating a sankey chart is to identify the entities and processes that need to be represented. Use a network diagram to organize the entities and processes and indicate how they interact with each other. Use labels to clearly identify each entity and process.
The second step is to select the appropriate color scheme for each bar. The bars represent the resource flow, and the color used to represent each bar will correspond to the color scheme selected earlier.
The third step is to assign values to each bar. The value can represent the quantity of resources being transferred between entities or processes.
The fourth step is to add a scale and labels to the chart. The scale shows the total value of the resources and their direction of flow. The labels on the bottom of the chart indicate the specific entities and processes being represented.
Using a Sankey Chart for Transformation
There are many ways that sankey charts can be used for transformation. One of the most common ways is to depict the flow of information between different departments or organizations.
For example, a company may have a central database that is responsible for managing customer information. The flow of information from this database to sales, marketing, and customer service teams can be demonstrated on a sankey chart. The chart can show the quantity of data being transferred from the database to each department, as well as the source and destination of the data.
Another use of sankey charts is to analyze budgets and resource allocations in organizations. The chart can show how the amount of resources being allocated to different departments or projects compare to the total budget for the organization. This allows managers to make informed decisions about how to allocate resources more effectively.
Sankey charts can also be used to demonstrate the movement of data between different data sources or sinks. For example, a company may have multiple types of data sources, such as customer information, product data, and sales data. These sources can be represented on a sankey chart as different bars, and the chart can be used to show how frequently the data is being shared or exchanged between the different sources and sinks.
Conclusion
In summary, sankey charts are a valuable tool for visualizing complex systems and transforming information. They can be used to demonstrate the flow of information in organizations, analyze budgets and resource allocations, and visualize the movement of data between different sources and sinks. By creating a sankey chart, organizations can create a clearer picture of how information flows within their systems, making it easier to make informed decisions about how to allocate resources more effectively.
