The document discusses GraphView tips for snapping nodes to a grid in Unity. It provides code snippets to: 1. Insert a GridBackground to provide grid lines. 2. Create vertical ports on a node and make nodes resizable. 3. Register a callback on the node's GeometryChangedEvent to snap its position and size to the grid on resize.
