The provided line graph illustrates the number of international visitors to three distinct regions—coast, mountains, and lakes—within a European country over a 20-year period from 1987 to 2007.
It is evident that all three regions attracted varying numbers of visitors throughout the period, with lakes experiencing the most significant fluctuation in tourist numbers.
In 1987, the coastal region welcomed approximately 20,000 overseas visitors, while the mountainous area attracted 30,000 tourists, and the lakes received around 10,000. Over the two decades, the coast demonstrated a consistent upward trajectory, culminating in a visitor count nearing 70,000 by 2007. Conversely, the mountains exhibited a fluctuating trend; after a peak of 30,000 in 2001, the number of visitors dwindled to just under 20,000 by the end of the period.
The lakes, in stark contrast, experienced a dramatic increase in tourist numbers, commencing at 10,000 in 1987 and ascending to roughly 80,000 in 2007. The most notable surge occurred around the year 2002, when visitation surged to approximately 75,000. Despite a subsequent decrease to 50,000 visitors in 2007, the overall trend for lakes showcased remarkable growth, surpassing the figures of both the coast and mountains by the end of the period.
