Sankey Chart in Tableau

Sankey Chart: A type of flow diagram that visualizes the flow of data or values between multiple entities.

Source and Target: In a Sankey chart, these represent the start and end points of the flow. In Tableau, these are typically dimensions like categories or labels.

Weight: The measure that determines the thickness of the flow between the source and target. It represents the quantity being visualized.

Node Values: Calculated values representing the magnitude of each node in the Sankey chart. Usually derived from aggregated measures.

Calculated Field: Use calculated fields in Tableau to create new fields or modify existing ones. Useful for deriving node values or other customized metrics.

Sorting: Arrange the nodes and links in a meaningful order. Sorting can be done based on the magnitude of the flows or any other relevant metric.

Formatting: Adjust the appearance of the Sankey chart to enhance readability. Customize colors, labels, and tooltips for better visualization.

Tooltips: Configure tooltips to display additional information when hovering over nodes or links. Provide context or details about the data.

Filters: Implement filters to allow users to interactively explore the data. Filters can be used to focus on specific categories or time periods.

Interactivity: Utilize Tableau's interactive features. Users should be able to click on nodes or links to see more detailed information or drill down into specific data points.

Parameters: Use parameters to create dynamic controls, allowing users to change certain aspects of the Sankey chart interactively.

Annotations: Add annotations to highlight important points or provide additional explanations within the Sankey chart.

Testing: Test the Sankey chart with various scenarios and datasets to ensure accuracy and optimal performance.

Performance Optimization: Optimize the performance of the Sankey chart, especially when dealing with large datasets. Consider data extracts and aggregations.

Storytelling: Use Tableau's storytelling features to create a narrative around the Sankey chart. Combine it with other visualizations to tell a compelling data story.

Data Connection: Ensure that your data source is properly connected, and relationships are established to support the Sankey chart's construction.

Data Quality: Ensure the data used for the Sankey chart is clean, accurate, and properly formatted.

Level of Detail (LOD) Expressions: Utilize LOD expressions in Tableau to perform calculations at different levels of granularity for more detailed analysis.
