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.
