Title: A Journey Through Dataflow Analysis: exploring sankey charts
Introduction
It is a common practice in data analysis to visually represent data flow using charts. Sankey charts are one of the most popular data representation techniques used in data analysis for its unique ability to show the flow of data. This article will explore how sankey charts work and their applications in detail.
Sankey Chart
Sankey chart is a type of flow diagram that can be used to represent data flow between different parts of an analysis. It is created by dividing the data flow into different segments, and then, connecting the segments with lines or arrows that point in a specific direction. The direction of each segment determines the direction of the flow of data from one source to the other. Each arrow represents the direction of data flow, while the length of each arrow represents the quantity of data.
Sankey chart can be represented as a rectangular grid with segments or as a circular graph with nodes and arrows. In both cases, the flow of data is represented using arrows, which show the direction and quantity of data. The segment or nodes represent the sources and destinations of data, while the arrows indicate the amount of data flowing through them.
Sankey Chart Applications
Sankey charts are most commonly used in data analysis to represent data flow between different sources and destinations. They are an excellent way to visualize complex and hierarchical data flows and also show how data flows in relation to each other. They are particularly useful in industries such as finance and healthcare, where data is often shared between different departments and systems.
There are many different ways to analyze data using sankey charts, and their applications are as varied as the industries that they represent. Here are some of the most common applications:
Analyzing customer data: One of the most common applications of a sankey chart is in analyzing customer data. For example, a retail store may use a sankey chart to show the flow of customers between different departments, such as sales, purchasing, and pickup. This helps to identify any bottlenecks or inefficiencies in the flow of customers and can be used to improve customer service and improve sales.
Analyzing supply chain data: Sankey charts can also be used to analyze supply chain data. For example, a company may use a sankey chart to show the flow of materials between different suppliers. This can help companies to identify any bottlenecks or inefficiencies in the supply chain and make necessary adjustments to improve overall efficiency.
Analyzing research data: Sankey charts are also used to analyze research data. For example, a researcher may use a sankey chart to show the flow of research documents between different researchers. This can help researchers to identify areas where information may be overlapping or duplicating, and can also provide insights into the types of information that is being distributed and reused by researchers.
Conclusion
Sankey charts are a powerful tool for representing data flow in a visual and interactive way. They offer a unique ability to highlight the flow of data between different sources and destinations, and their applications are as diverse as the industries that they represent. By using sankey charts, data analysts and researchers can better visualize and understand complex and hierarchical data flows, and use this information to make data-driven decisions.
