Introduction

Sankey charts offer an intuitive way to visualize complex data relationships and interactions that can be difficult to describe with traditional bar or pie charts. This article will explore the power of sankey charts, providing a visual guide to their creation and applications. Whether you’re a data analyst, researcher, or student, you’ll find the information provided both enlightening and useful.

Understanding Sankey Charts

A sankey diagram is a visual representation of data flow or material flow, usually involving the direction of flow or movement across networks. It’s used to show the relationships between different entities or areas, with the flow direction representing the direction of the movement of a particular commodity or resource.

Designing a Sankey Chart

To create an effective sankey chart, start with a clear understanding of the data you’re working with. Identify the components of your data set, whether they’re geographical, economic, or social in nature, and then assign a specific color or symbol to each component.

Next, identify the flow direction, or key, that connects different components in your network. This connection might be explicit or implicit, depending on the nature of your data set. Depending on the complexity of the network, it might be simpler to select a few key components and define their flow direction.

The flow direction can be defined as either arrow or line, and it is often specified through the use of labels or annotations. The arrowhead or label indicates the direction or flow of the flow, whereas the line itself indicates the movement.

Once you have a clear understanding of the data flow and the components involved, the final step is to plot the data on the chart. Use the arrows or lines to accurately depict the direction of the flow and the volume or intensity associated with each key component.

Application of Sankey Charts

Sankey charts have various application for businesses, academic institutions, or governmental agencies. In the academic sphere, they can be used to represent educational programs or research activities, highlighting the relationships between different stakeholders or programs. In business, they can represent supply chains, production, or marketing, highlighting the flow of resources or goods between different departments or facilities.

In government, sankey charts can represent the distribution of resources or economic activity, including infrastructure, industry, and education. They can help policymakers visualize the interconnectedness of the public sector and highlight areas where improvements are needed.

In Conclusion

Sankey charts offer a powerful visual tool for analyzing complex data relationships and interactions. They can help data analysts and researchers communicate complex information in clear, intuitive ways, making it easier to understand and analyze the data. With their ability to visually represent data flow or material flow, sankey charts are an essential tool for anyone working with data.
