    Study Notes

    Sankey Diagram Fundamentals

    • The Source column defines the start node of the arrow in a Sankey diagram.
    • The Count value is used to scale the size of the connecting flow in a Sankey diagram.
    • The Target field represents the end node of the arrow in a Sankey diagram.

    Creating a Sankey Diagram in Flow.BI

    • To create a Sankey diagram in Flow.BI, users need to drag and drop fields in the Sankey diagram chart builder to specify Start and End nodes.
    • Customizing a Sankey diagram includes setting the title, axis labels, and other options.

    SQL Lab and Sankey Diagrams

    • To create a Sankey diagram in SQL Lab, users need to write a SQL query to visualize the results, not a Python script.
    • The SQL query should include SELECT source, target, SUM(value) AS value FROM sankey_data GROUP BY source, target ORDER BY value DESC.

    Sankey Diagram Best Practices

    • Interactivity can enhance a Sankey diagram by allowing users to explore the data.
    • Using a clear and concise title is important for a Sankey diagram to effectively communicate the data.
    • A recommended practice is to use annotations or labels to highlight key findings in a Sankey diagram.
    • Considerations should be made for an audience with no prior data knowledge when creating a Sankey diagram.
    • The width of the arrows in a Sankey diagram represents the value of the flow between nodes.

    Sankey Diagram Misconceptions

    • A common misconception is that the Source column defines the destination node in the chart, which is incorrect.
    • The Target field does not represent the magnitude of the flow between nodes.
    • The width of the arrows in a Sankey diagram does represent the value of the flow between nodes.
