Sankey charts are a versatile and powerful tool for visualizing complex relationships between data. These charts are often used in fields like economics, social sciences, and engineering, where understanding complex interactions is essential. In this article, we’ll explore the history of sankey charts, their advantages over other visualization methods, and steps to create your own sankey chart.
A Brief History of Sankey Charts
The concept of sankey charts can be traced back to the 18th century, where it was used for statistical analysis and financial planning. At that time, sankey charts were primarily used by surveyors and merchants when mapping out complex networks of goods and resources. They were later adopted by economists, who used them for analyzing supply and demand curves and other complex economic relationships.
Current Uses of Sankey Charts
Sankey charts are often used in financial services, where they help understand the flow of money and its impact on businesses. In the engineering field, they are useful for visualizing the impact of a network of resources on a project, and in social sciences, they are used to track the distribution of wealth and resources among diverse populations.
Advantages over Other Visualization Methods
One of the main advantages of sankey charts over other visualization methods is their ability to show relationships between variables in a visual format. Other methods, such as bar graphs and pie charts, are often limited to showing categorical data. Sankey charts, on the other hand, make it easy to show the flow of information between multiple variables, which allows for a more comprehensive understanding of complex relationships.
Steps for Creating a Sankey Chart
Creating a sankey chart is relatively straightforward. Here are the steps you’ll need to follow:
-
Identify the variables you want to visualize.
-
Assign a color to each variable. You can use colors that reflect the value of the variable.
-
Choose an axis for the x-axis. This will represent the variables.
-
Use arrow directions to show flow between variables. Use arrows that flow from higher values to lower values.
-
Label each component of the chart you create. This will help make the chart easier to understand.
-
Add dimensions to the chart. This can be done by adding additional rows or columns to the chart.
-
Customize your chart to suit your needs. This can include changing colors, adjusting the axis, and adding other visual elements.
In conclusion, sankey charts are a powerful tool for visualizing complex relationships between data. Whether you’re working with economics or another field, sankey charts can help you gain a comprehensive understanding of relationships between variables. By following the steps for creating a sankey chart, you can create a clear and intuitive visualization of your data.
