The line graph illustrates the number of commuters who transport by subway during a day from 6 am to 10 pm in the capital of British.

From an overall perspective, while most people take underground at the time when they go to work in the morning and come back home in the evening, the lowest number of passengers belong to the time of early morning, the end of a day and around 4 pm.

It can be seen from the chart, beginning at about 100 people in the early morning, the number of passengers experiences a significant increase to peak at over 400 people over the period between 8 am and 9 am. After rush hours, this figure considerably falls by approximately 220 commuters at ten and a half and then gradually recovers to nearly 300 after 1pm. Nevertheless, before reaching the second highest point with under 400 passengers at 17:30 pm, it bottoms out at roughly 90 people. In the rest of the day, it plunges to a dip of about 120 commuters. Only during an hour from 19:30 to 20:30, is there a slightly growth by 100 passengers.
