Sankey charts are a type of network or flow graph that are incredibly effective at visualizing complex data. Unlike some other network or flow graphs, which can be quite intimidating and hard to understand, sankey charts make it easy to understand the flow of information or objects between different points. In this article, we’ll take a closer look at how sankey charts work and some of the applications they can be used for.
First up, let’s take a look at some of the concepts behind sankey charts. A sankey chart is based on the concept of flow graphs, which graphically represents a flow of information or objects between different points. In a sankey chart, we typically visualize three values: the source, the sink, and the flow. A source is represented by a node with an arrow pointing out of it, indicating the direction of the flow. A sink is similarly represented with an arrow pointing into the node, indicating the reverse flow. Finally, the flow is represented by a line connecting the source and sink nodes along their length.
One of the great things about sankey charts is that they make it easy to see the flow of data between different points. For example, imagine that you have a series of data points that represent user behavior on different pages of a website. You could represent this data using a sankey chart, with each node representing a website page, each arrow representing the flow of user behavior from the page to the corresponding page, and each line representing the amount of traffic flowing on that particular page.
Another example of a sankey chart might be used to visualize the flow of money through a company’s finances. A sankey chart would allow you to visualize the flow of money from each source (such as employee salaries, marketing expenses, and financing), to each sink (such as sales revenue, marketing expenses, and taxes), and to each component of the business (such as employee salaries and marketing expenses). This type of visualization can be extremely useful for understanding the financial health of a company and for making informed decisions about resources allocation.
Sankey charts can also be used to represent any type of flow or information, such as the flow of information in a library, the flow of information between different departments in a company, or the flow of information between different time periods. They can be particularly effective at visualizing complex information in a visually intuitive way.
One of the great advantages of sankey charts is that they can be used to create a wide range of different types of visualizations. For example, you can create sankey charts to visualize the flow of money in your company, but you can also create sankey charts to visualize the flow of information in a library or the flow of information between different departments in a company.

In summary, sankey charts are a powerful tool for visualizing complex data. They are based on the concept of flow graphs and are particularly effective at visualizing the flow of information or objects between different points. sankey charts can be used to create a wide range of different types of visualizations, and there are many different types of sankey charts available. They provide a visually intuitive way for people to understand the flow of information or objects between different points, making them a useful tool for understanding complex data or information.
