The given line graph compares three different areas (coast, the lakes, and the mountains) in terms of the number of tourists in each European country from 1987 to 2007.

However, it increased sharply to just 50,000 in 1997 and then reached a peak of 75,000 in 2002, and it remained unchanged until 2007. The lakes were the second popular destination for visitors from 1987 to 2002. Initially, the number of tourists visiting the lakes started at around 20,000 in 1987, then this figure rose to exactly 25,000 visitors by 1992. This area saw a rapid growth in the number of travelers over a decade, reaching a peak of 60,000 visitors in 2002, before falling to 50,000 by 2007.
