Sankey charts are often overlooked when it comes to data visualization, but they can be a powerful tool for visualizing complex relationships between different data elements. In this article, we’ll discuss the basics of sankey charts, their applications, and how to create them yourself. We’ll also explore some creative approaches to using sankey charts in your data visualization projects.
What is a Sankey Chart?
A sankey chart is a type of flowchart that uses interconnected linear segments to show how data flows between different points in a network. The basic structure of a sankey chart consists of several linear segments, called nodes, and connected by straight lines (also called links). Each node represents a different data element, and the connections between the nodes illustrate the flow of data between them. Typically, sankey charts use two colors to represent different types of data. One color represents input data, while the other color represents output data.
Sankey charts can be used to visualize a wide range of data relationships, such as the flow of money between different sources and sinks, or the flow of information between different sources and sinks. These charts can be used to show the relationships between different types of data, such as between variables in a dataset.
Applications of Sankey Charts
Sankey charts can be applied to a variety of data sources and types of data relationships. For example, they can be used to visualize the movement of money between different financial institutions, the flow of news articles between different sources, or the flow of information between users of a social media platform. They can also be used to visualize the relationships between variables in a dataset, such as the flow of sales between different products or services.
There are several advantages to using sankey charts over other types of data visualization. First, sankey charts use a linear representation of data, which can make it easier to understand the relationships between different data elements. Second, sankey charts can display both input and output data, making it possible to explore the flow of information in different directions. Finally, sankey charts are often more intuitive to understand than other types of flowcharts.
Creating a Sankey Chart
Creating a sankey chart can be done by hand or using software. Most sankey charting tools support both methods, and many also allow for automatic node placement and data labeling. Creating a sankey chart requires selecting the nodes and links, and adding them to a template or document. The template often includes placeholders for the data elements, which will be replaced with input/output data. It’s also important to label each node and link, and to make sure all necessary data sources and sinks are properly indicated.
Some creative approaches to Using Sankey Charts
Sankey charts are not just a way to visualize data relationships. They can also be used for creative ends, such as creating infographics or designing visual reports. Here are some creative approaches to using sankey charts:
- Using a different color for each node or flow direction, to show hierarchy or flow direction.
- Using different colors for different types of data, to show differentiation and categorization.
- Using sankey charts with different types of layout and spacing, to show complexity and structure.
- Using sankey charts with dynamic node placement, to show real-time data flow or update.
In conclusion, sankey charts are an often-overlooked data visualization tool, but they can be a powerful tool for visualizing complex relationships between different data elements. By understanding the basics of sankey charts, as well as exploring creative approaches to using them, you can create compelling visualizations that will help you communicate your data more effectively.
