Sankey charts are a type of data visualization that are often used to explore the relationships between different data sources. They are particularly effective for displaying the flow of information or data between different elements. In this article, we will explore the secrets of creating a Sankey chart and give you some practical tips on how to use it in your own projects.
The Basics of Sankey Charts
A Sankey chart is made up of three main elements: a start node, an end node, and connecting lines. Each line represents a particular data source or value, and the length of the line corresponds to the source of the data. The start node represents the data source or area of interest, while the end node represents the destination.
Creating a Sankey Chart
The first step in creating a Sankey chart is to identify the data sources and values that you want to visualize. Once you have a list of your data sources and values, you will need to decide on the dimensions of your chart. Sankey chart can be created in two main formats: rectangular or circular.
If you choose the rectangular format, you will need to create a rectangular grid with the start and end nodes at the top and bottom of the screen. You will also need to create a number of lines connecting the different data sources. If you choose the circular format, you will need to create a circular grid with the start and end nodes in the center of the chart.
At this stage, it might be helpful to create a design mockup of your chart before going any farther. This can help you make the most of the available space and ensure that your chart is visually appealing.
Once you have created your grid and lines, you can add your data sources and values for each line. You will need to make sure that the size of each line corresponds to the magnitude of the data it represents. It is also important to ensure that the order of the data sources makes sense in terms of the flow of information.
The end node of each line will be where the data is being processed or consumed, and it is important to have enough information on this axis to visualize the flow of data effectively.
Using Sankey Charts in Your Projects
Sankey charts can be used in a variety of applications, such as understanding the flow of information in a marketing campaign, tracking the flow of revenue or expenses, or visualizing the distribution of data across different variables.
If you are creating a Sankey chart with a circular format, you can use it to show a breakdown of different data sources across different segments of a customer base. For example, you could break down customer loyalty by age group, gender, or income level and visualize the relationships between these groups.
If you are creating a Sankey chart with a rectangular format, you could use it to show the flow of information from a central source to other areas of the organization. For example, you could create a Sankey chart showing the flow of money being spent on different departments, which could help you to understand where the budget is being allocated and identify opportunities for cost savings.
In conclusion, Sankey chart is a powerful tool that can help you to understand the flow of information or data between different elements. By following the steps outlined in this article and making sure that your chart is visually appealing and effective, you can use it to make informed decisions and better understand the relationships between different data sources.
