Effortlessly Navigate Data Flows with Tableau Sankey Charts

A Sankey diagram is a visualization that shows the flow of data or material from one set of values to another. In Tableau, you can create a Sankey diagram using the “Sankey” mark type in the “Show Me” menu, or by manually setting up the chart using a dual-axis bar chart and customizing the appearance.

Tableau Sankey charts, also known as Sankey diagrams, are a type of visualization that is used to show the flow of data between different stages or categories. They are particularly useful for showing how data is distributed or distributed across different categories and how the different categories are related to each other.

To create a Sankey chart in Tableau, you will first need to connect to your data source and drag the dimensions that you want to use for the source and target of the flow to the Columns and Rows shelves, respectively. 

Then, you can drag a measure to the size shelf to control the width of the flow. Finally, you can right-click on one of the dimensions in the view and select “Sankey” option to change the mark type to Sankey.

Some of the key features of Tableau Sankey charts include:

• They can be used to show the flow of data between different stages or categories.
• They are particularly useful for showing how data is distributed or distributed across different categories and how the different categories are related to each other.
• They can be used to display data in a summarized or detailed format.

To create a Sankey diagram in Tableau, follow these steps:

1. Select the “Sankey” mark type from the “Show Me” menu.
2. Drag a dimension to the “Path” shelf. This will be used to differentiate the different elements in the Sankey diagram.
3. Drag a measure to the “Size” shelf. This will be the value that the Sankey diagram displays.
4. Drag a dimension to the “Color” shelf. This will be used to differentiate the different paths in the Sankey diagram.

You can customize the appearance of the chart by right-clicking on the chart and selecting “Format.” From here, you can change the color scheme, font, and other visual properties of the chart.

Sankey diagrams are often used to show the flow of materials or information through a process or system. They can be useful for identifying bottlenecks or inefficiencies in a process, and for understanding the relationships between different elements in a system.
