Sankey charts are a type of data visualization that can help you to compare and contrast different segments or groups of data. This type of chart allows you to see multiple sets of data on the same graph, which makes it easy to compare different variables or categories. Sankey charts are particularly useful in situations where you need a visual representation of complex data.
What are Sankey Charts?
Sankey charts are used to create graphs that represent the relationships between two or more systems. Each point on the chart represents a flow of data, and the shapes of the shapes determine the type and direction of the flow. Common examples of Sankey charts are food chains or energy flow diagrams.
Why Use Sankey Charts?
Sankey charts are useful when you need to analyze complex data and understand the relationships between different variables. Whether you are studying the flow of information, energy or materials, Sankey charts allow you to see the flow of data from one point to another, which can help you to identify trends and patterns in the data.
How to Create a Sankey Chart
Creating a Sankey chart requires some knowledge of data analysis and visualization techniques. Once you have the data you want to visualize, you can use a data analysis software package, such as Excel or SPSS, to create the chart. The process is relatively simple; you first need to create a matrix of data to represent the relationships between different variables, and then use the matrix to create the Sankey chart.
What are the Applications of Sankey Charts
Sankey charts are widely used in various fields, such as biology, economics, engineering, and medicine. In biology, Sankey charts are used to visualize the flow of chemical and biological molecules in a cell. In economics, Sankey charts are used to compare the flow of different economic factors, such as income, wealth, and prices. In engineering, Sankey charts are used to visualize the flow of materials and energy in a piping system, or the flow of information and data in a network. In medicine, Sankey charts are used to visualize the flow of substances and blood flow in a patient.
