Nov 8, 2007 - Graph Analysis Practice

The graph shows the everage daily use of the D.C. metro. During the day, 8am and 6pm imply the highest number of passangers use and the lowest at 6am and 4pm. From 6am to 10am, the spiked shape of the trend could be attributed to the rush hour people hurrying to work. From 10am to 4pm, there is a rise and then falling shape but not that sharp owing to the lunch time. From 4pm to 8pm, there shows a spiked shape of trend again due to the rush hour people are off duty to go back home. In summary, the D.C. metro is much more crowded at 8am and 6pm than at the other time during the day.
