The provided line graph depicts the changes in the number of international tourists visiting three distinct areas in a European country during the 20-year period from 1987 to 2007.
Overall, it is evident that there was a remarkable increase in the number of overseas visitors to the coast and lakes, while the mountain areas experienced fluctuating figures without any significant growth.
The coast and lakes experienced substantial growth in visitor numbers, with the coast rising from around 20 thousand in 1987 to over 70 thousand by 2007, and the lakes witnessing a surge from approximately 10 thousand to around 80 thousand during the same period. However, the mountains only saw a slight increase of about 10 thousand visitors by 1997 but then experienced a fluctuating decline, reaching just under 20 thousand visitors by 2007.
In the last decade, the number of visitors to the lakes dramatically rose to over 70 thousand in 2002, before experiencing a sharp decline to around 50 thousand by 2007. Conversely, the coast consistently saw an increase, exceeding 70 thousand visitors by the end of the period. Similarly, the number of overseas visitors to the mountains slightly increased to around 30 thousand by 2007.
