Sankey charts, also known as directed acyclic graph (DAG) charts, are a powerful and versatile tool for visualizing complex datasets. They are particularly useful for analyzing and presenting data that involves directed relationships between different components or elements. In this article, we will explore the basics of sankey chart creation and applications to help you unleash the insights hidden within your data.
Step-by-step guide to constructing sankey charts:

1. Understanding the concept of a sankey chart: A sankey chart is formed by connecting different elements with directed lines. The flow of information between the elements is depicted by how the lines connect. The direction and flow of information is indicated by the orientation and direction of the lines.
2. Choosing the appropriate dataset: The first step in creating a sankey chart is choosing the appropriate dataset to visualize. It is crucial that the data is detailed enough to provide useful insights and that the dataset is in a format that can be easily read and understood.
3. Identifying the key components and elements: Identify the key components and elements that will be included in the sankey chart. These can include people, organizations, services, processes, technologies, etc.
4. Creating the sankey structure: To represent the relationships between the components in the sankey chart, create a sankey structure by connecting the components. Typically, the top-left corner represents the origin or source of the information, and the bottom-right corner represents the destination or sink of the information.
5. Adding labels to the components: Add labels to the components to indicate their type and purpose. These labels can be customized and customized to improve readability.
6. Adding weights to the sankey structure: Adding weights to the sankey structure can be used to reflect the importance of each component. The weight of each component represents the amount of information or flow that is attributed to it.
7. Customizing the display style: Customize the display style to make the sankey chart more visually appealing and easy to understand. This can include different color schemes, markers, and labels.

Sankey chart applications:

1. Analyzing and presenting complex data: Use sankey charts to analyze and present complex data sets that involve directed relationships between different components or elements.
2. Tracking progress and success: Use sankey charts to visualize progress and success in a project, task, or process.
3. Tracking customer journeys: Use sankey charts to track customer journeys and identify potential bottlenecks and opportunities for improvement.
4. Tracking the flow of work: Use sankey charts to track the flow of work among team members, projects, and tasks.
5. Tracking social and political movements: Use sankey charts to visualize the flow of information during social and political movements, such as protests or political campaigns.

In conclusion, sankey charts are a powerful tool for analyzing and presenting complex datasets, and they can be used to unleash insights that may be difficult to identify otherwise. By following the step-by-step guide on creating a sankey chart and utilizing it appropriately, you can make complex data accessible and easy to understand.
