Sankey charts, a type of visual representation of network data, have gained immense popularity in data science and business analytics. These charts are often used to visualize the flow of resources, such as money, materials, or human skills, through a network of relationships. In this article, we will explore the basics of Sankey charts and how they can be used to unlock insights in data visualization.
What is a Sankey Chart?
Sankey charts are a type of network diagram that visualize the flow of resources through a network of relationships. The chart consists of two main components: the source element (the starting point) and the target elements (the end points). The source element has a value associated with it, while the target elements have value dependencies on the source elements.
For example, suppose we have a network of organizations that send and receive products through a supply chain. In this case, the source element would be the manufacturer, and the target elements would be the distributors and retailers who then sell the products to consumers. By using a Sankey chart, we can see the flow of products from the manufacturer through all the organizations in the supply chain to the consumers.
Sankey charts can be used to unlock insights about the organizational structure of a company or a network of relationships between different entities. By using the colors, thickness, and connectivity of lines in the chart, we can gain a deeper understanding of the relationship between different elements in the network and potential bottlenecks or redundancies.
How Sankey Charts Can Revolutionize Data Visualization
Sankey charts can revolutionize data visualization because they offer several advantages over traditional network diagrams. Firstly, Sankey charts allow us to easily compare different elements in the network by using different colors or hues, making it easier to identify the most significant elements. This makes it easier for us to spot areas of strength or weakness and pinpoint the most critical flow of resources.
In addition, Sankey charts are visually appealing and easier to read than traditional network diagrams. This makes it easier for people to understand complex data visualization and identify key insights without the need for technical expertise.
Another advantage of Sankey charts is that they can be used to visualize more complex networks of relationships. For instance, by analyzing the flow of resources across different industries, Sankey charts can reveal the dependencies between different sectors, helping us identify areas for growth and opportunity.
Moreover, Sankey charts can be used to generate actionable insights. By analyzing the flow of resources through different layers or segments, analysts can identify inefficiencies or bottlenecks in the network and develop strategies to improve the flow of resources efficiently.
Conclusion
Sankey charts are an excellent tool for unlocking insights in data visualization. By visualizing the flow of resources through a network of relationships, we can easily identify areas of strength or weakness and gain a deeper understanding of the organizational structure or the relationships between different entities in the network. By using Sankey charts, we can gain deeper insights into the data we are working with, and this can help us make better decisions, improve our operations, and increase our efficiency.
