Sankey charts are a powerful visualization tool that can help you easily see the flow and transformation of your data. This type of chart is often used in conjunction with network diagrams, and it can provide a clear and intuitive representation of complex data sets. In this article, we will explore the basics of Sankey chart creation, as well as some of the many ways that these charts can be applied to help you better understand your data.

What is a Sankey chart?

A Sankey chart is a type of flowchart that is used to represent the flow of materials, money, or information through a system. The chart is named after William Sankey, an American statistician who developed the technique in the early 20th century.

The chart consists of a set of nodes, each of which represents a flow or transformation of some kind. These nodes are connected by arcs that represent the flow of the data in question. The arrows on the arcs can be directed either towards or away from the nodes, depending on the direction of the flow.

One of the key features of Sankey charts is that they use a set of standard symbols and icons to represent different types of flows and transformations. This makes it easy to read and understand the chart, even when the underlying data is complex or abstract.

How is a Sankey chart created?

There are a few different ways to create a Sankey chart, depending on your needs and the tools you have at your disposal. Here are some of the most common methods:

1. Using software like Microsoft Excel or Google Sheets:
   These popular spreadsheet programs include a built-in Sankey chart function that makes it easy to create and edit Sankey charts. You can import your data into these programs and use their built-in formulas and functions to create a chart.

3. Using a spreadsheet library or API:
   There are a number of libraries and APIs that allow you to create and work with spreadsheets programmatically. These can be useful if you need to automate the creation of Sankey charts, or if you need to perform complex calculations or customizations on the chart.
