The line graph illustrates the number of enquiries received by the Tourist Information Office in one city over a six-month period in 2011, categorized by in-person, letter/email, and telephone.
Overall, the data shows a clear trend towards more in-person and telephone enquiries, while the opposite is true for letter/email. This indicates a preference for more immediate forms of communication, with people increasingly favoring direct interaction or calling over written communication during this period.
In January, telephone enquiries were the highest at around 900, followed by letter/email and in-person enquiries, both at about 750. By February, in-person and telephone enquiries were similar at around 800, while letter/email remained constant at the same level.
From March onwards, in-person and telephone enquiries increased significantly. In-person enquiries reached nearly 1900 by June, and telephone enquiries rose to around 1600. In contrast, letter/email enquiries consistently declined, dropping from 700 in March to just under 400 in June.
