Introduction:
Data visualization is the act of presenting data in a way that is easy to understand and communicate with others. This can help explain the relationships between different variables and can aid in decision making. One powerful tool for data visualization is the Sankey chart. In this article, we will explore the basics of Sankey charts, creation, and applications.
What is a Sankey Chart?
A Sankey chart is a type of diagram that can be used to visualize relationships between different elements or values. It has a specific shape that resembles a pipeline, with the size of each element depending on the value or resource it represents. The basic structure of Sankey charts follows the same pattern as a flow chart but with a different type of data visualization.
Sankey charts are commonly used in projects that require tracking and managing resources, such as projects, budgets, and supply chains. They are also used to visualize complex relationships between variables such as energy flow, flows of finance, and processes within an organization.
Creating a Sankey Chart:
Creating a Sankey chart is relatively simple once you understand its basic structure. Below is a step-by-step tutorial on how to create a Sankey chart:
1. Define the elements: Identify the different variables or values that you want to visualize on your chart.
2. Determine the flow of elements: Decide on the direction of each element and the direction in which it flows into or out of other elements.
3. Size the elements: Assign a specific size to each element that reflects its value or significance.
4. Identify gaps/empty loops: If there are any gaps or empty loops in your flow chart, consider reorganizing the elements to ensure accuracy and clarity.
5. Connect the elements: Connect the elements together to form the flow charts you want, and add labels to each element and gap to indicate the direction of the flow.
6. Customize the chart: If you haven’t already, you can customize your Sankey chart with color, shading, and other visual elements to make it more informative and readable.
Applications:
Sankey charts can be used in a variety of fields including finance, supply chain management, project management, and emergency management.
1. Finance: Sankey charts are used to visualize the flow of finance in an organization, including investments, loans, and repayments.
2. Supply Chain: Sankey charts are used to illustrate the flow of resources in a supply chain, including raw materials, components, and finished products.
3. Project Management: Sankey charts are used to track progress and allocate resources in a project. This helps in planning, monitoring, and control.
4. Emergency Management: Sankey charts are used to understand and visualize the flow of resources in an emergency response. This helps emergency management teams to coordinate their efforts and communicate the situation effectively.
Conclusion:
In conclusion, Sankey charts are a powerful tool for visualizing relationships and tracking data. Whether you are a data analyst, business executive, or policymaker, Sankey charts can help you communicate complex relationships between variables and make informed decisions. The basic steps and applications of Sankey charts outlined in this guide should help you create effective and informative diagrams to visualize your own data.
