The flow of data is an essential aspect of data analysis. With the emergence of data visualization tools, understanding the flow of data in a more visual and intuitive manner has become easier. Sankey charts, a method that uses nodes and arcs to represent flow of information, data, or business processes, has emerged as one of the most popular visualization tools, especially in the field of management and business. This article will give an in-depth look at Sankey chart creation and applications.
Sankey charts are also known as flow maps and are used to represent the flow of data from source to sink entities, or in the case of business processes, the flow of information from one node to another in a network. For example, in a company where different departments handle different parts of a project, in a financial model where stocks flow into different accounts, or in a marketing funnel where leads flow from the top of the funnel to the bottom, a Sankey chart can be used to represent this flow of data in a more visually appealing and informative manner.
Sankey charts can be created using software tools such as Tableau, Power BI, or even Microsoft Excel, among others. However, the simplest way to create a Sankey chart is using online tools like Google Charts or Canva. Although these online tools can generate the basic concepts for designing a Sankey chart, it is essential to know the basics of design to create a visually appealing and informative Sankey chart.
In the basic design of a Sankey chart, the nodes represent the source and sink entities (or accounts in business), and each source node is connected to a single sink node using a single straight line to represent how the data flows through the network. The thickness of the line and the position of the node depends on the volume of the flow and can provide additional insights. The arcs represent the direction of the flow of data, typically represented by a lighter color and line, and the label for each arc can be added to provide information about the source and the destination nodes.
To create a more dynamic and interactive Sankey chart, you can use the drag and drop feature. Users can move the nodes and the arcs as they see fit, and can change the direction of the flow.
In addition to basic Sankey charts, there are more advanced Sankey charts that use color to represent different attributes of the flow of data. For example, each node can have multiple arcs and each arc can have multiple labels that represent different attributes of the flow of data. This allows users to get a more detailed understanding of the flow of data than with a simple Sankey chart.
In conclusion, Sankey charts are a versatile and effective tool for data visualization, particularly in the field of management and business. They can be used to represent the flow of data from source to sink entities and in the case of business processes, the flow of information from one node to another in a network. Online tools for generating simple Sankey charts provide an easy entry point for data visualization, and advanced Sankey charts using online tools allow users to customize their visualization to meet their specific needs.
