Sankey charts are a type of network diagram that are widely used in the sciences and social sciences to visualize complex relationships between variables. They are also an excellent tool for creating interactive visualizations. In this article, we will explore the secrets of how to create and interpret sankey charts.

Creating a Sankey Chart
A sankey chart consists of three main components: input (inputs), output (outputs), and flow (sources and sinks). The sources and sinks are represented by arrows on the chart, and the flow between the inputs and outputs is depicted as lines with different colors.

To create a sankey chart, start by deciding the variables you want to visualize and assigning values to them. Next, create a network diagram that represents the relationships between the variables. You can create a grid for inputs and outputs, and arrows to indicate the flow of information or resources.

For each input, calculate the amount of flow that goes to each output. You can use mathematical formulas to determine the flow between the inputs and outputs.

The flow between the inputs and outputs can come in different colors, which can help you understand the direction of the flow. For example, if you have negative flow, you can indicate it by a different color to indicate the direction of the flow.

Interpreting Sankey Charts
Once you create your sankey chart, you can use it to interpret complex relationships. You can create a visual representation of the flow between the inputs and outputs by filling in the chart with color. For example, you can use different colors to indicate the direction of the flow (inputs, outputs, or both).

Sankey charts can also be used to highlight important variables or relationships. To highlight a variable, you can color it differently or by displaying it as a separate group in the chart.

Sankey charts can be a powerful tool for understanding complex relationships and decision-making processes. They can help you understand how variables are related to each other and their impact on a system.

In conclusion, sankey charts are a great tool for visualizing and interpreting complex relationships between variables. By creating a sankey chart, you can create a visual representation of the flow between the inputs and outputs of the system and use it to interpret the relationships between the variables. Sankey charts are a versatile tool that can help you understand complex systems and make better decisions.
