Sankey charts are unique data visualization tools that provide a clear, concise representation of the flow of data between different elements or entities. Used in fields ranging from economics to social sciences, Sankey diagrams allow users to easily visualize complex data sets in a simple, intuitive way. In this article, we will explore how Sankey charts can help increase data visualization’s power, transforming the way in which data is represented and communicated.
Understanding Sankey Charts:
Before diving into the art and science of Sankey charts, it’s important to understand what makes them unique. A Sankey diagram typically consists of a central node representing the overall flow of data, connected to a chain of “flow” nodes that represent different elements or entities. Each flow node is labeled with the quantity of data being transmitted through that particular channel. When you draw a Sankey chart, all you need to know is the data flow between two nodes and the labels you want to use to label each node.
How to Use Sankey Charts Effectively:
Once you have a basic understanding of what a Sankey chart looks like, it’s time to start using them to their full potential. Here are a few ways that Sankey charts can help data visualization:
1. Simplify Complex Data
Sankey charts can be used to simplify complex data sets, making it easier for people to understand the flow of information. For example, when analyzing the growth of revenue from different products, you could use a Sankey chart to visualize the flow of data, highlighting which products contributed the most to revenue growth.
2. Enhance Understanding of Complex Relationships
In fields such as economics or sociology, Sankey charts can help analyze complex relationships between different variables. For instance, in econometrics, you might want to understand how different factors like market size, price, and demand impact the supply and demand for a particular product.
3. Communicate Data in a Clear and Concise Way
Sankey charts allow you to communicate data in a clear and concise way without relying on extensive text. This can be particularly useful when summarizing large data sets or when trying to communicate a complex idea to a non-technical audience.
Applications of Sankey Charts:
Sankey charts have a wide range of applications in fields such as social sciences, economics, and public health. Here are a few examples:
-
Economics and Business: Sankey charts can be used to visualize the flow of data between supply and demand chains, production, and the overall economy.
-
Health Care: Sankey charts can be used to analyze the flow of data between patients, treatment centres, and health institutions, aiding in decision-making about resource allocation.
-
Environment: Sankey charts can be used to visualize the flow of carbon emissions, air pollution, and waste management.
-
Sustainability: Sankey charts can help visualize the flow of resources between ecosystems, human activities, and conservation efforts.
Conclusion:
Sankey charts have the power to transform data visualization and communication. By using them effectively, you can simplify complex data sets, enhance understanding of complex relationships, and communicate data in a clear, concise way. Whether you’re analyzing revenue growth, supply chains, or natural resource flows, Sankey charts can help you unlock the full potential of data visualization.
