The provided line graph illustrates three different ways to obtain information at a tourist office in England between January and June. The units are measured in numbers.
Overall, a quick glance reveals that there is an upward trend in both the amount of requests for information in person and by telephone except by letter/email. It is also worth pointing out that, while the number of desires to get knowledge by telephone was the highest at the beginning of the period in January, the number of requests in person became the highest at the end of the period.
Turning to the details, one feature of the diagram is that in January, while the amount of desire to get information by telephone was approximately 900, the letter/email was just under 800 and the person was just above 400. The number of demand to reach information by letter/email fell slightly around 700 in March, and then there was a dramatic decrease through 2 months. After May, it levelled out over the next period.
Additionally, it is also important to note that, while the number of desires by telephone dropped moderately exactly 800, before rising slightly until March, the number of requests in person increased significantly and then they met at the same number with 1000 between March and April. After April, both of them climbed sharply over the next period, the number of demands in person was around 1900 and the telephone was exactly 1600 at the end of the period in June.
