Sankey charts are a type of visualization that can be used to explore and understand complex dataflows. This article will provide a brief introduction to sankey charts, their power, and applications, and will also include a step-by-step tutorial on how to create your own sankey chart.

What is a Sankey Chart?
Sankey charts are a type of flowchart that is used to visualize the flow of a system where a flow of entities, such as people, objects, or resources, go through specific nodes and links. The primary aim of sankey charts is to highlight the different types of entities, the movements of entities through the system, and the resources needed for each entity type.

Sankey charts are particularly useful in situations where you have a complex dataflow or system that you want to understand. They can be used to illustrate the different components of a system and the connections between them, helping to identify areas where improvements or changes may be needed.

Applications of Sankey Charts
Sankey charts have numerous applications in different fields such as business analytics, social sciences, and engineering. Some of the common applications include:

1. Analyzing project workflows: Sankey charts can be used to visualize the different types of tasks involved in a project, highlighting their dependencies and timelines.

2. Analyzing energy flow diagrams: Energy flow diagrams can be created using sankey charts to show the different types of energy sources and their usage in a system.

3. Analyzing resource allocation: Sankey charts can be used to analyze resource allocation in a distribution system, helping companies to optimize their processes.

4. Business process mapping: Sankey charts can be used to map business processes, highlighting the different types of tasks and their dependencies.

Creating a Sankey Chart
Creating a sankey chart is relatively straightforward, and there are several resources available online to help you get started. The following steps outline the basic steps to creating a sankey chart:

1. Gather your data: Before creating a sankey chart, you need to gather all the data you need to include in the chart. This can include the types of entities, the movement of resources, and the dependencies between them.

2. Determine the structure of the chart: Sankey charts usually have nodes at the bottom and links at the top. Each node represents a type of entity, and each link represents a dependency or relationship between two types of entities. You can customize the nodes and links to fit your data.

3. Create the chart: Once you have all the data and the structure, you can start creating the sankey chart. You can use software such as Microsoft PowerPoint, Tableau, or other similar tools to create the chart.

Tips for Creating an Effective Sankey Chart
The following tips can help you create an effective sankey chart:

1. Use a clear and concise design: Ensure that the sankey chart is simple and clear, with the most important data displayed prominently.

2. Use colors to highlight dependencies: Using colors to highlight dependencies can help you identify relationships between entities and can make the chart more visually appealing.

3. Keep the chart simple: Avoid cluttering the chart with unnecessary data, keeping the chart simple and focused on the most important data.

Conclusion
In conclusion, sankey charts are a powerful tool for visualizing complex dataflows and can be used in various fields. Creating a sankey chart is relatively straightforward and requires only basic design skills. With the right design approach and some practice, you can learn to create an effective sankey chart and unlock the hidden data in complex systems.
