- When you bring the pointer close to a bus, a four-headed arrow appears. Left-click and drag to move the bus.
- When you move the pointer close to the either end of the bus, a double-headed arrow ↔ appears. Change the size of a bus by dragging either end of it with the left mouse button. You can even shrink it to a single dot or “node” so that it takes up less room.
After experimenting with moving and sizing the buses, arrange them as shown below.
