Summarise the information by selecting and reporting this main features and make comparisons where relevant.

The line graph compares the number the foreign visitors to three different areas, namely the coast, the mountains and the lakes, in a European country over a period of 20 years.
Overall, the number of overseas tourists visiting those areas increased between 1987 and 2007, with the coast being predominant for most of the time and the lakes experiencing the most significant changes in the number of visitors.
In 1987, coastal area had the most travellers (40,000 people) but underwent a slight decrease by roughly 5,000 people over the next 5 years. In contrast, the number of overseas visitors to the mountains and the lakes, which stood at 20,000 and 10,000 respectively in 1987, both had risen to about 25,000 by 1992.
Then, from 1992 to 2007, the number of visitors to the lakes had the most striking changes. After gradually increasing for about 8 years, it skyrocketed and peaked at roughly 75,000 (about 13,000 more than that of the coast) in 2002 but then declined to 50,000 in the final year. During that time, there was a gradual climb in the number those visiting the coastal area, which was about 75,000 in 2007. That of the lakes in the final year was more or less 35,000 after fluctuated between 20,000 and roughly 35,000.
