Overview
The node graph exposes control but creates visual complexity. Searching for nodes, renaming them, and understanding connector types are necessary skills; otherwise, the graph becomes difficult to modify safely.
Preview Image reduces unwanted files but adds a manual save step for good outputs. Save Image is convenient when every output should be retained, but it also saves failed or experimental generations automatically.
The graph must remain type-correct. A visible image cannot be connected directly to a latent input, and latent data cannot be previewed without VAE decoding. These conversions are not optional visual details; they are required transformations between data representations.
