This setting chooses which link Value totals determine node size.

• Out - size by outgoing flow (default): sum of values on links where the node is the source.
• In - size by incoming flow: sum of values on links where the node is the target.
• |In-Out| - size by the absolute gap between incoming and outgoing totals, so nodes with a large imbalance appear larger.

Final size is still mapped between Min Node Radius and Max Node Radius. Use Relative Sizes on a category to scale nodes only within that category.
