This field must contain a numeric value. The value will be used to determine the node size (smaller values = smaller nodes, larger values = larger nodes). The value of each row in this column defines how much is passed from source to target.

You can adjust how the visual handles value display by using the Value Format (in the Nodes (Default Category) section) or Value Format (in Node Category X) settings. Choose between IN (value is ‘passed down’ to target nodes), OUT (value is ‘sent up’ to source nodes), or a combination of both.
