The line graph illustrates the volume of inquiries received by the Tourist Information Office in a specific city over a six-month duration in 2011, categorized into three distinct methods of communication: in-person visits, letters/emails, and telephone calls.
Overall, there is a notable increase in in-person inquiries, while the other two methods exhibit contrasting trends, particularly a decline in letter/email correspondence.
Focusing first on the in-person inquiries, there is a remarkable upward trajectory throughout the six-month period. Starting at approximately 200 inquiries in January, this figure escalates dramatically, reaching nearly 1800 by June. This consistent rise indicates a burgeoning interest in personal visits to the Tourist Information Office, suggesting a growing reliance on face-to-face communication by tourists seeking information.
Conversely, the inquiries made via letter/email show a substantial decrease over the same period. Initially, this category recorded around 1000 inquiries in January, but by June, it had plummeted to approximately 400. This downward trend highlights a significant shift in communication preferences among the public. In addition, telephone inquiries demonstrate relative stability, starting around 800 in January and experiencing a slight decline to just under 600 by June. This indicates that while there is some fluctuation in this method, it does not reflect the more dramatic changes observed in the other two categories.
