How graph flow works

A graph is a procedural recipe made from connected nodes. Each node creates data or changes data from an earlier node.

An output port sends data. An input port receives data. A connection carries the data from the output port to the input port.

Flow matters because Goblin Node evaluates upstream sources before downstream results. A Checker node can feed Box Blur, which can then feed Graph Output.

Checker -> Box Blur -> Graph Output

Graph Output identifies a result that the Output preview and export tools can use. A branch that does not reach an output can still appear in the Selected preview.
