The timeline diagram above for the ATM withdrawal system shows three main components: the bank, the ATM machine, and the customer. Each section is represented by a large square box with a set of states shown on the right side. Progress over time is shown on a small scale below, while the varying lines above show the different states status over time. This timeline shows the duration and sequence of various processes in the system, from card to cash. It provides a comprehensive overview of the time taken for each step and when each state is active.
